Ford F-150 - 1997-2003 :: Surge Or Stall Out When Slow Down Sometimes
Nov 5, 2013
I have a 97 F150 with a 4.2. It has started to surge or stall out when I slow down sometimes. It doesn't do this all the time. I replaced the fuel filter about 2 mths ago and replaced the fuel pressure regulator then also. Would the tps have anything to do with it? I haven't had a scan done yet. Thought I would try here first because at one time someone has removed the two cats and the check engine is on all the time.

I have a 2003 silverado with a 4.8 engine. i bought the truck in the summer of 2010. no problems in the winter of 2010. ran great all year in 2011, then my block heater shorted out in the winter of 2011, so i wasn't able to plug the truck in.
We get some cold nights up her in alberta, but anything below -10c the truck would idle surge and stall, would do this about 4 times in a row then it would just surge a few times but stay running.
I had a buddy that's a gm drive ability tech take the truck and do a tone of updates for the throttle body and to correct idle surge and some other drive ability related stuff. i cleaned the maf, map and tps as well as the throttle plates. replaced plugs, wires, air filter and fuel filter. all this and it was still doing it, but it had to be really cold to stall.
wasn't able to replace the block heater till this summer. but now that its getting colder and dropping below -10c at night the truck is starting to idle surge when i start it up in the morning.

7.3 2001 model starts ok at 32-35 F. Feels a bit sluggish / slow response on the road. Reach a hill after 3-4 miles. Engine temp then beginning to go above low level mark. 100 meters up the hill, going around 30 mph there is a sudden surge in the throttle although my pedal is steady. Going back a few minutes later, on flat ground at bottom of hill and with no accelerator pressure, the engine suddenly stalls. Starts fine again after I stop. The same history actually repeated on two separate days recdently on the same hill. CPS is recently replaced. Had some jerking before that, but not the behavior explained above. Current CPS is Delphi light grey. Recent fuel filter change and oil change as well

This started about a month ago. The truck surges at any speed as long as the gas pedal is at a static position. There are no codes. I have replaced the fuel filter air cleaner cleaned the maf and did a ton of reading on this issue. Is it the tps? The tps voltage does not fluctuate any when it surges. Maf,? Should be throwing a code right? Same as the egr valve. What am I missing?

I just changed my 4.6L. Now my tranny is starting to serge and buck it won't go in rev. But when I put it in D it started to clunk and buck. RPM would go up speed went down.

I have a 97 F150 4.2l auto 4x4. The truck seems to surge or hesitate at pretty much all speeds. I have had the truck on fords so-called super "sbds" computer and they found nothing. I am taking it tuesday to have the o'2 sensors and CAT. Convertors checked at a local parts/service store. Also found out today that my speedometer is 5 mph to slow (doing 65 but speedo only registers 60).

I have a 2002 F150 5.4 2 valve. only when the engine is cold, everyone once in a while the engine will surge up and down about 2-300 RPMs for about 10 seconds. also right when I put it in drive it will surge. I was thinking about pulling off the trottle body and cleaning it.

I have a 2005 f252 6.0 diesel with electronic climate control and when my a/c comes on it surges/stalls my truck and throws several codes (P0108, 0403, 0405, 2104, 2123, 2138, 2139, 2140) and disables my gas pedal. I know I am loosing my 5v reference, but not sure where. I have replaced my compressor, alternator, both batteries, low pressure switch, accumulator, oriface tube.
I've disconnected several 5 v reference sensors and all gives me the same results. if I disconnect my low pressure switch my defrost and heater works fine and no issues, but this is not engaging my compressor. when I plug the low pressure switch back in , the same issues happen, I checked my fuses, and swapped the relay in the battery box. Looking for drawings of the circuitry or wiring diagrams.

I have a 01 f-150, 4.6L, with 160k miles on it. Symptoms: It idles fine with an occasional surge. It sputters in all gears like a misfire (all plugs and COPS replaced 2 months ago). Sometimes it stalls out going down highway or as I turn in my driveway. It also seems like its slipping a little without the "hard jerking into gear". Occasionally the rpm meter will peg low and then return to normal.
The only code that I received was P1451. I changed the canister vent solenoid but the symptoms remain. I've checked voltage on the TPS (the variable voltage checked out but I didn't get the 5V ref. voltage). I've cleaned the MAF sensor. I've also changed the fuel filter. I've resistance checked the connector to the PCM and found several pins that are at ground. I'm not sure what to do next.

Been awhile since I've been on here...guess that's a good thing! Current problem...about a week ago my car stalled after starting it. I had been running errands all day so the engine was warm. Started fine, and then slowly died. My husband replaced the IAC valve. (My truck had this same problem 3 1/2 years ago...it was the IAC).
After replacing this time, it seemed to be fine. However today, again after running errands, the engine stalled slowly after I had started the engine. It seemed like it was trying to stay running, but then just slowly died. I tried starting again and it stayed running, so I was able to get home. It seemed to run fine while driving home. Also, no engine light has come on. Wondering what could be causing this. Don't want to get stranded somewhere.

I have a 2000 f150 with 210000 miles. The truck wants to stall when coming to a stop. I have noticed this from a higher speed and more when at operating temp. The truck runs great and idles at a stop great, but when coming to the stop the rpms drop to300 or so then it catches itself and revs up. I have cleaned the maf sensor the iac and checked throttle body all seem to be in working order and no obvious vacuum leaks.
My power steering pump is going and it's time to change plugs, but don't believe these would only effect the truck at braking. Have heard maybe torque converter is stuck this does make sense cause usually happens after getting out of first gear. Would changing the fluid solve this or should i look at sensors? Fluid starting to turn slight brown probably been in there 80000 miles.

2001 F150 V8 4.6 Liter... I've been experiencing hesitation when first pressing the gas, stall at idle, RPM fluctuating between 1000 and 500 at idle and loss of acceleration. Had the truck read at autopart store and received a P0402 error and misfire is cylinder 8.
At this point, I've changed the the plug, COP, EGR valve, EGR Valve Solenoid and DPFE sensor and still have the exact same symptoms. I've also changed the plug for cylinders 5,6 & 7 as well. The check engine light is on, went off briefly after changing DPFE sensor, but back within a day.
Given the fact the error code is P0402 and some of the threads I've read, I thought the issue was centered around the EGR system, but I've replaced many of the components.

I have a 99 f150 with 171xxx miles and the other day it suck in second gear and start shaking and misfiring and would stall out. I took the truck and got the codes read and it threw codes for the tcc solenoid and shift solenoid. I put both in the transmission and it kepy doing the same thing. I check fuse 24 under the hood and it was blown, I replaced it and everything worked fine for a day then it blew the fuse 2 more times and i cant figure out why it is blowing that fuse. I cant find any shorts maybe pcm??

I have a 2002 4.6L FX4. When I run the A/C for an extended period (say 15-20+ minutes), it will start to cough and sputter and eventually just die. It will restart but run rough and cough, sputter, die.
If I turn off A/C and let it set a while, it runs fine. No check engine light. Possible EGR problem????

So.... here's my issue. I have a 2001 supercrew 5.4 and runs great all day long, no problem starting or anything. After I have driven it for a while and turn the AC on it cools off very good then after about a 1/2hr. the truck tries to stall. It almost sounds like a vacuum leak and really bogs down. I can wait about 2hrs and then with the AC off the truck starts and drives like it should. I am steering to the IAC valve but would like to know if this is it.

I have a 98 f150 that I don't drive often. I had it out tonight and realized the my brake lights wouldn't come on unless I pressed the peddle down hard. Does the switch work off of pressure? They used to come on as soon as I would touch the peddle.

My windshield wipers on my 97 f150 go very slow. Not sure if it's bad motors or what but I find it weird for them both to go at the same time. Is there a relay that could be causing this?

My 03 with a 5.4 has been hesitating a when you accelerate and cutting out as well as idling rough and die when you slow down. It does all this intermittently. Not every stop or every time you accelerate. I first got a code for the MAF and both banks running rich (PO102, PO172, PO175) so I cleaned the throttle body and MAF. The running rich code came back (PO172, PO175) so I then changed the MAF and air filter . It seemed to work for a day or so then my light came on and I figured the same code was back but to my surprise it was now both banks running lean(PO171, PO174) so I took my MAF back and got another one. It hasn't set a code yet but it is still running poorly. I have changed all the COP's and plugs as well ....

OK, after some bearing issues I replaced the crankshaft with a reman. The engine is now in, but it is not turning over like I think it should. It just feels too tight, and cranks slow. It cranks smooth, nothing hitting. It is hard to turn with a wrench on the front bolt. I am wondering if I messed up on the torque on the rod bearings.
I torqued them according to the book. First to 29 to 33 ft lbs, then rotated an additional 90 to 120 degrees. I went with the lower of the numbers, 29 foot pounds then an additional 90 degrees. The mains I tightened to 30 ft. lbs. then an additional 90 degrees.
Are these the correct specs? I did smear a little grease on the main journals before installing, but did not do this for the rods as the book says. Is this maybe something to do with my issue?
I did not measure with plastiguage to see, I didn't realize I was out of the stuff and didn't want to drive 50 miles away to get some! I am also wondering if heating up the bearings on one rod journal might have warped the rod and is binding not allowing it to turn. I did notice when I put it back together it turned a little hard, but figured it would be ok once it started.

I have a 03 f150 2wd with the 4.6l. Recently it has been slow shifting into reverse(about 2 full seconds) and when it finally gets in reverse it shudders when it comes under load. The fluid is full and not burnt...
