Ford F-150 - 1997-2003 :: Truck Keep Stalling On Acceleration
Mar 10, 2015
my 97 f150 4.2L keeps stalling on acceleration. It ran fine this morning then my wife put 20 dollars of fuel in it and drove 30 miles to her destination with no problem. on her way back the truck started bucking bogging down and acting like there was a fuel problem but it didn't kill. I checked for codes there were none. I removed the fuel filter on the rail and replaced it with a new one. Now it will idle fine with no miss but if I give it gas it kills.
I checked the codes again there are none. I also checked to make sure there was fuel coming from the tank when I turned the key as well as making sure I heard the fuel pump kick on when I first turned the key.I am leaning towards water in the fuel,i didn't see any trash come out of the old filter, however I am not sure. I have a 175 mile commute to and from work.

I have a 2003, 4.6 F-150 with 201,500 miles
I am having some A/C issues. It's just too hot out there.
#1 The truck has a lack of power when I have the A/C on. It feels like it wants to stall out in the lower RPM's. I loose power when I go 65mph+. The truck actually stalled on me yesterday in the parking lot. I turned off the A/C and it ran fine.
#2 I have to go over a 5000ft pass daily, I turn off the A/C when I go over it. Below the pass, the A/C doesn't work well and it's not as cold. But when I get over the pass, the A/C turns very cold. The pass is like a 3-4 mile stretch.

I have a 2003 Excursion 4X4 V10 (6.8l) gas with 130K.
About six months ago, the truck started stalling at irregular intervals. The truck runs fine for weeks at a time, but will suddenly die. This happens at idle, and under power. After stalling, the truck usually starts back up, but there has been a few instances where I thought it sounded fuel starved. It has stalled as many as four times in a row (within 15 minutes), but shortly after it runs fine again.
I researched this board, and tried the following: cleaned the MAF, and replaced the IAC Valve.
But, it stalled again, so in late February I took it to the dealer; a AAA approved repair facility which means they guarantee the fix for two years.
The dealer claimed to have pulled a P0231 code. As a result, they replaced the fuel pump and assembly, along with the fuel filter.
The truck ran fine until two weeks ago, then it went thru a series of stalls again. In each instance, the truck started right up, and I drove it to the dealer.
The dealer took it in again and had it for six business days, but they could not replicate the issue. I suggested they test the PCM/fuel relay and the signal going to the fuel pump - they said everything checked out okay. No charge, the ticket remains open.
What could be causing this? I am not too good with electrical stuff; in fact, I know very little. Another member explained a way to test the signal at the time the truck stalls, but I am not sure if I could competently do it. I am thinking I need to start replacing part after part until it stops? I don't mind doing that, but would need to know which parts to focus on. Should I start with the MAF? I cleaned it, but do not know how to test it.

This just started happening last week. When I put the truck into reverse, the engine lugs down and dies. It' as if the AT is fully engaging reverse gear with no clutching action. If give the truck a bit of pedal, I can put her in reverse and back up without issue. Going forward into Drive has no issues.

2001 f350. 7.3 has 350k on the engine. Last week it cut out and stalled it was about 15 degrees and though.. fuel had jeld... it warmed up.. didn't happen again. Then two night ago.. happened 4 times in a row then it was fine. yesterday a dozen times at least. It stalls but restarts itself (roll starting i guess) the water in fuel ,CEL and wait to start lights come on and then go off. We started with fuel filter, have changed the cam position sensor (yes with ford part not part stores) and now have also changed the Injection pressure sensor (also with ford part) while it needed changed as it was leaking oil the truck is Still stalling.
My dad is a technician He hooked his computer to the truck.. nothing. He was able to get the truck to recreate the problem with the scanner hooked up. When it stalls if he holds the throttle down the truck stays at an idle and the CEL, wait to start and water in fuel lights are on. It decelerates and puts along as nice as you please with the fuel peddle to the floor! let off the accelerator, lights go off and it recognizes the throttle again. No codes at all. hes thinking its the pcm telling the icp to shut off fuel. What would cause it to do that?

My brother has an 03 GA GT. The car recently started bogging down on acceleration. It tops out at about 25 mph, and full throttle causes the car to stall. He was throwing a code for the egr valve, and replaced that. Then he threw a code for maf sensor, swapped it and no change. We've also changed the MAP, TPS, IAC, O2, Coolant Temp sensor; so far, no luck. I don't know much about these cars?

Like the title says my truck has been stalling while driving. Accelerating or cruising it dies for a second, two at the most, and then just keeps chugging along again.
I thought i'd fixed the problem last year when I did injector O-rings and 50 cented my UVCH. It hadn't done it since, until two days ago. Started out with a two good solid stalls while gently accelerating up hill. I had thought maybe my fuel pickup foot had finely given up the ghost because I was below a quarter tank. But I filled her up full, and then she did it again about 50 miles of driving later.
I didn't catch the first four stalls on my torque app, because I'd just recently decided to stop logging every trip, with the thinking that it had been half a year problem free, why keep logging waiting for something that isn't going to happen. I did catch the 5th stall on the torque log. But I'm having trouble trying to figure out where it happened in a 30 min log.
First question where would yall start in tracking this thing down? Next what data actually should be logged? I think I've got some extra stuff in my logs that isn't necessary, and is maybe bogging down the system. I get one data point per second resolution on my logs. Are there ways to improve the resolution, will getting rid of some PIDs work?
Lastly I need to attack this thing smartly, without throwing time and money at unneeded parts. I had surgery and I've been out of work for 3 months and I'm looking at another 6 before I'm making money again, and there is no unemployment for the self employed. Also I only get 3-4 light weight upright hours a day to work, exceed that and I'm back on the couch battling swelling for a week.
Also is there anything I can do while driving to "flag" the stalls so I can find them more easily in the logs?

I have a 2003 f150 2WD crew cab with a 4.6 V8 engine it has 178,000 miles on it. The other day after I started it to leave work it died on me without hesitation almost like the ignition switch was turned off I tried to restart and it would turn over but wouldn't start so I switched the ignition all the way off and it started right up, going down the road it did it again.
If I try to restart without turning the ignition all the way off it won't start but if I turn it all the way off it will start up first try, it has done it a couple times since and its the same way every time, where to start. My check engine light has been on for some time for something else so I don't know if it picked up a code or not I don't have a code reader to see if it has a new code...

I've recently had problems with my truck running 97 f150 4.2L.The latest episode is it stalling when coming to a stop. It will start right back up, I've checked for codes and found none, I have changed the fuel and air filters and I have tested the fuel pressure.(I have a video of the test however I don't know how to upload it.) Key on engine off it pumps up to 30 immediately on the gauge. key on engine running gauge shows a steady 32. I am really at a loss for what to check next. I really need this truck dependable again ASAP my wife is scared to drive it.

2002 f150 7700 with 5.4 triton and 4r100 tranny started chugging under acceleration and now stalls when put in D, 2 or 1. park and neutral are fine and reverse works perfectly.
Now when I put it in drive it chugs and stalls immediately... 1/10 times it will keep running but chug violently like its running out of gas. will get worse and stall if you press the gas. i can light the tires up for a block in reverse however.
Changed coils 1 2 and 3, IAC, bank 1 knock sensor, camshaft position sensor

I recently got a 2wd 1994 150 straight 6 4.9L, It's been a great truck so far. It drove from New Mexico to California with no issues. Just this morning it started stalling and dying when pulling up to stop lights and putting it in reverse. The truck has 172,000 miles and has a new serp belt, alternator, radiator, and starter. It seems to run just fine on the highway and once it's warmed up it doesn't stall as easily. There is an exaust leak.

My 2002 f350 7.3 was given to me in July of this past year. I was 15 at the time and I was told that it was hydrolocked. Funny enough this is where I came to learn how to fix it, and this is the first time I have had to ask a question . I pulled both heads and replaced all 8 injector cups, I also had the heads re surfaced and had 7 injectors rebuilt and 1 replaced. I got it on the road in February around the 20th and since then I have put about 300 miles on it. Today I stopped at a red light and made a left turn and as I went to accelerate the truck jolted forward a few times and it felt like a tire was going to fall off while accelerating(only to 30mph). I pulled into a driveway to check all the tires, then I turned around and my foot was hard to the floor and the truck wouldn't go over 15. Diddn't smoke when it first happened, but after getting it off of a flatbed I turned it around and it hardly had enough power to get up my driveway. And I noticed it was pushing a steady stream of white smoke, the oil is clean and the oil cap doesn't get blown off at idle when I set it upside down on the valve cover.

It's been a long time since I have posted here mainly because my truck was wearing a bow tie for awhile. But my wife was nice enough to tell me the Bow Tie wearing truck was making a funny noise on New Years Day (seems a small drum corps took up residence in the oil pan). So anyhow now I am back in a real truck . My new to me 1998 F150 5.4 Liter ran fine until yesterday. It started idling rough and almost stalling at red lights. about halfway home the CEL light came on and is throwing a P0171 code.
So far I have checked for vacuum leaks including all the elbows on the PCV system' tried the spray test with a can of flammable break fluid and a can of starting fluid (man I love the smell of that stuff) could not find a leak. Cleaned the MAF sensor and the K&N air filter (not a fan of these) IAC seems to be working. Only thing I know that is leaking for sure is the driver side exhaust after the cat. But that is the wrong bank if I am correct on which bank is which.
So why only one bank running lean and why does it act like it is only firing on 4 cylinders?

2 questions regarding our 2001 F150 Supercrew. My 2 questions are:
My 2001 Ford F150 Supercrew (5.4L, 230,000 miles)has the check engine light on with the code reader telling me that it is the P0174. The truck would run rough when cold (usually in the mornings) and sometimes it would get close to stalling out when coming to a stop light. So we would quickly put it in park and give it some gas to rev it up a bit. After the truck gets warmed up, it runs great with no hint of the rough idle. Since this all started I have changed out the PCV valve and replaced the PCV hose (including the elbow). I have also replaced the Idle Air Control unit but that didn't really make a difference.
We then experienced a cylinder #4 misfire which we resolved by changing out the cop with a new Motorcraft unit. The misfire went away but we still had the problem of running rough at idle to the point of stalling out at stops when the engine is cold. A few weeks ago we cleaned the MAF sensor and that seemed to work. The truck doesn't run as rough now (when cold) at stop-lights, but occasionally it will still have the loping idle. We cleared the check engine code and it stayed off for about a week before returning.
I don't know what else to check other than trying to see if there is some type of vacuum leak, but I don't have access to a smoke machine nor would I know how or where to hook one up. Removing and cleaning the throttle body would work? What could be causing the trouble, or what I should do to further isolate or troubleshoot the problem? I saw a you-tube video on the F150 intake manifold gasket possibly being the problem and although I hope that isn't the trouble with my truck, if it is then I will have to deal with it. We need the truck to get to work and the car is now due for a registration renewal, but we can't get a California smog certificate with the check engine light on.

So I was given a 1999 f150 4.6. The transmission was supposedly either new or rebuilt. (I'm going with rebuilt) Driving it for the first time today, I noticed it had very little poor acceleration. When I would get on the gas (to the floor) the rpms would shoot up (3-3.5) but the truck didn't accelerate accordingly. It feels like the power it's getting to the wheels. Driving at highway speed trying to maintain a speed at over 70 the truck wanted to stay at 2500 rpms but if I let off the gas just a touch it would shift up (into overdrive I think) and level out at just below 2000 rpms, but if I accelerated even just barely, it would down shift and go back to 2500. I've also noticed the truck runs 5 mph faster than it reads with stock sized tires. I've check the tans fluid and it is bright red in color and at the appropriate level. I crawled under the truck and noticed the trasfer case mount was wet with fluid (not dripping) and the rear output shaft of the transfer case was also wet. Could this be a transfer case problem?

Need some input on miss firing on acceleration on a 2001 Ford SuperCrew F-150 Lariat, 5.4 engine. 200,290 miles.
Have replaced all spark plug boots covers (Sept 2012), number 1 plug (Sept 2012), 3 and 7 plugs replaced, 3 and 7 has heli-coil kits (2011) installed for blown out plugs. New in-take manifold (2010). New gas line filter, air and oil filters (Oct 2012) and oil changes every 3000 to 3500 miles. Have poured 12 oz. fuel injector cleaner in gas take two times with 6 to 7 gallons of fuel in gas tank (last 2 weeks).
Have No check engine light on for service engine but have had an diagnostic scanner analyzer plugged into driver side, in cab outlet, 4 different times to see if I have a bad coil on plug or other problems. No codes show up indicating any problems. The engine idles nicely when at stop lights but does have a slight intermittent miss at times when warmed up and stopped at lights. Engine misses when warmed up on acceleration (when it is under a load and on acceleration).
Had a mechanic tell me he could plug an analyzer into engine but couldn't guarantee he would find anything wrong. This sounded like a little snow in July to me and the mechanic didn't sound optimistic.

I've had this truck since 2011. Ran great when I got it. Ive had problems with the calipers and I've replaced both the fronts. I keep up on changing the oil regularly. The manifolds started rusting away a little over a year ago. Not happening... The shaking started recently after I pulled a trailer with 2.5 tons of shingles on 2 separate occasions.
That being said, I can feel a little shaking while idling. It was really only bad between 500 and 2000rpms. After 2000 it almost felt like a turbo and it would accelerate really fast and smooth until the gears switched. I figured i should change the oil. Now the shaking is more violent.
Its a 2000 f150 5.4 v8....

I have a 97 f150 with 4.2 4x4 auto. I have a bad miss under acceleration. if i ease on the gas no problems. stomp it and it chugs and pops back thru airbox til it gets to 2500 rpm then clears up. If I shift it manually and keep rpms up its fine till it gets below 2500. I have replaced spark plugs, plug wires, fuel filter, upper and lower intake gaskets, cleaned injectors, new air filter and cleaned o2 and mas sensors. Had vacuum system checked and was told all good.

I have a 2001 F150 4x4 5.4l with 105k miles. I started it up today to go to lunch and it made a knocking sound on start up that lasted maybe 20 seconds. So i shut it off and checked oil. All ok. Started it up again and it knocked but not as long as it did previously. I started to drive and higher in the rpm range before the trans shifts it makes the same knocking sound. Left off the pedal it goes away then rev it again it doesn't make the knock till around 2000rpm mark it I remember correctly. It makes the noise in all gears, parked or driving. It runs great, no power loss or misfire. Could it be a spark plug on the verge of blowing out or is it time for a new motor? I am going to look at it more tonight when I get off work.

2002 Model, F150, 4.6L Triton....
Early last week one day my truck just wouldn't start. I had driven it the day before. but that day nothing. It would spin over just not start. the following day though, it started as always, no hesitation and run smooth. But the was the last day it has ran.
Since then I have checked the relays and fuses. I have checked the inertia switch (pass. side kick panel). Removed the cap on the schrader valve on the fuel rail. (no pressure)
I have sprayed starting fluid into the throttle body and it starts for 1 to 2 seconds. (dies once starting fluid is gone). I have changed the fuel filter and pulled the bed and changed out the fuel pump. I'm thinking about trying the fuel pressure regulator next.
Just not real sure where else to go if that doesn't work.....
