Ford F-150 - 1997-2003 :: Hiccup Or Slight Lurch When Accelerating Just After Coasting At 50 Mph
Jun 30, 2015
I have a 2002 Ford F150. 273,000 miles on it. When I am going about 50 mph and I start down a hill and let off the gas a bit and then when at the base of the hill I push on the gas to accelerate then sometimes it does a weird hesitation or slight "lurch" but it is NOT in the engine. The engine continues to run smoothly during this lurch. It only happens between 45 and 55 mph. It only seems to happen when I am trying to accelerate out of a coast. I had the dealer check underneath thinking it might be a u-joingt? They said everything underneath seems to be in good shape. Someone told me to consider Ring and Pinion Slop problem in the rear differential? When I read about that it seems that it normally makes a noise. There is no noise with my truck's problem.

I have a 2002 f150 5.4L 4x4 7700 and she was misfiring bad the other day I changed coil pack 1 and 4 because that's what my codes where reading and i changed all of my spark plugs just because the check engine light went away for a little over a day and boy was she running good she had a little hiccup with a misfire but it quickly fixed itself but later now my check engine light is back on and is miss firing again and this time it isnt fixing itself what is going on with my truck?

When coasting to a stop, I have noticed when the rpms reach 1000-1100 they jump up a little bit. Sometimes you can even feel the car lurch forward just a tiny bit. Is this normal for a car downshifting??

My 2003 Ford Ranger XLT FFV V6 has been chirping when I accelerate, generally louder the quicker I accelerate. It stops when I am not touching the gas pedal (coasting). It does not chirp in reverse.

I was coasting down a steep hill yesterday when the CEL came on. I pulled the code this morning and got code P0174, system too lean bank 2.
I cleared the code. Should I just wait to see if it happens again? The truck is running great. There is no sign of a problem. BTW, it's 99 F150 5.4.

I have a slight issue. A few weeks ago, I put some "STP" style fuel injector cleaner into my gas tank. Either A) It cleaned everything really well and clogged my injectors, or it turned into gunk and possibly clogged something else up.
Ever since that day, my issue is that the car "stutters" very slightly. When idling, it'll "hiccup." When I'm doing normal driving, 55-60mph at 2k RPM, It'll almost feel like a transmission slip.
I've went and replaced my Fuel pump, filter, and now I've done half a can of seafoam through the brake line power booster (vaccuum) straight into the engine, and the other half into my oil for further cleaning. I also applied Seafoam Deep Creep into my throttle body, just for further maintenance.
Ever since then, everything has been running noticeably better, and I've had a huge increase in gas mileage, but there's still a slight hiccup that occurs during idle and driving.
I change the oil /filter, plugs, wires, air filter on a regular basis.
I also had to change the MAF at one point in time, as it died and the car wouldn't start at all.
Next thing I'm thinking about doing is changing the plugs / wires one more time (it's been about 5 months since my last change) just to see if I bought a faulty plug.
The car was put on a computer and the only error code that came up was one about my check engine light being out.

All, i have an issue ( or at least i think its an issue) with my 99 f150 5.4. When i use my cruise control, i notice when i put on the brakes slightly to slow down, it feels like its not coasting because you can feel the engine still engaged and wont coast. I think this happens even without the cruise on. What this could be? I have the latest update on the cruise control harness. I believe that was for power always to it even in off, causing fires.

My car has three codes P0102 - MAF or VAF Low Circuit Input, P0030 & P0050 which are signaling O2 sensor issues.
Car symptoms are a hiccup type sputter when accelerating for the first few times after starting the vehicle. The RPMs will drop down under 1000rpm and it will come back without taking my foot off the gas. The power comes back faster if I flutter the pedal. The last few times it stalled while taking off.
After the car is warm, it runs better smoother. I'm also noticing slightly poor fuel economy. The exhaust smells rich to me.
I'm wondering if there is a fuse that could cause all three codes? Seems like a power problem? Where is the fuse for these sensors?
Should I replace MAF? Can I use the MAF from a 2004 2.4L engine that's at the junk yard? How to proceed.

I have an issue with a 1993 Ford Tempo. It is owned by a auto parts store and is used for deliveries so it gets a lot of use from day to day. Several different mechanics have looked at it and no one can figure out exactly whats wrong.
The issue is this - The car stalls out at about 2 or 3 oclock everyday after being used for deliveries starting at 9 oclock. It will stall while idling in park, while stopped in drive, while coasting/accelerating in drive. The temperature is normal. Is will start to idle and run very rough and the car is less responsive to the gas pedal about 10 minutes before it stalls.
Once it stalls, if it is allowed to sit for about half an hour it will start and run fine for a little longer but eventually stall again. After it sits for a few hours it is fine to run for a few hours again. If you try to start it right after it stalls the first time the engine will turn over but stall out again in a few seconds, if you keep trying to restart it it will eventually not even crank. Also it will occasionally stall like this/run rough in the first 10-20 minutes of driving.

I've began noticing about 2 - 3 months ago that while coasting up to 50-55 mph my truck begins to hesitate with a slight banging when it occurs. At first I was worried it may have been transmission, but once I talked to ford mechanics, they reassured me it was not, especially at 85,000 miles. I then noticed that taking it out of overdrive prevents the problem. It doesn't act up unless I am on the highway between 50 and 60 mph. It seems to progressively get a little worse and occasionally I can feel a jolt, as if it's struggling to shift into OD. What the problem could be? 2006 F-150 FX4 ...

I haven't really gotten under it to check this out, but my truck (see signature) has a slight vibration on take off. It only does it when the wheels are turned to the right or left. They don't have to be turned very far either. It doesn't do it on straight line take offs, or on a take off from a rolling stop. ONLY when pulling off from a dead stop and the front wheels are turned any degree to the right or left. I'm running mostly bald all terrain tires, the wheels are not bent. My current wheels are new to the truck, and the problem was there with the previous rim/tire combination. The rear end doesn't seem to have any slack in it. The transmission shifts like a top. There are no other clanks or vibrations anywhere in the drivetrain and it drives good.

So today I got to 800+ miles and when I'm coasting in gear... When I get it to the point (by the gas pedal) where the transmission is not loaded so you can slide out of gear...(you guys that understand power shifting know what I am talking about...) I hear a whirling noise.... Whoo-Whoo-Whoo- etc...I hear it sounds near the clutch (guesstimating since its near the front/dashboard)
I would have to drive it another 500 or so miles to get home. No mods, started trip with about 300 miles... Did not use cruise control.. Varied speed around 60-90 mph to keep the rpms moving since there isn't a lot of mileage here... Idk what else to say... This is really bugging me... Never launched the car... And I did search, only results I got was from other parts of the forums saying wheel bearing...

I have a 2000 F-150 xlt off road with a 5.4. I have owned the truck since 2001. The truck has 170K miles on it and I change the oil between 3-4K miles. The last couple oil changes I have I have noticed I haven't been draining as much out as I usually do, this past oil change was about 3 quarts low. I thought it was very odd. The truck runs great and does not smoke or leak oil.
This morning I got in and noticed a tick or slight knock, thought maybe it needed warmed up. After a minute. I shut it off and checked the oil, to my surprise there was next to no in the engine! This has me very worried now. I haven't checked my coolant since last oil change so I'm not sure if that's where it's going. Where to start looking, I'm missing like 5 quarts of oil in 3300 miles. Again the truck run great and does not smoke at all. I was getting ready to change it this weekend, always run high millage 5w-30.

Recently noticed when driving, I'll hear and feel a slight clicking noise coming from my steering column. I can be going straight or turning. it is intermittent. I've look underneath and nothing seems obvious. when the truck is in park, I've tried to manhandle the steering wheel, the steering wheel is solid. the truck is a 1998 f150xl v6.

I have 2002 f150, fx4, ext cab, 110000miles 5.4 automatic truck, i just replaced my spark plugs, it still have a little miss, thought spark plugs will resolve but its the same, im wondering if i should change O2 sensors? clean EGR Valve? IAC valve? i am not getting good gas mileage and maybe its this missfire or something, its runs good without any problems, just this slight miss makes me think if its the cause to bad MPG.
I tried to find threads with pictures of how to change O2, how to clean EGR, and IAC, i remember seeing these threads but cant find em. And you think these three things will resolve my MPG and the slight miss?

I have a 2001 f150 5.4 with 200,900 miles. Just bought the truck about six months ago off my dad when he got a new one. I am now experiencing what seems to be a slight misfire. With the hood up pulling the throttle around 2200 rpm starts making a loud knock. Above that rpm nothing and below that nothing. Standing by the tailpipe it sounds like a small backfire. It Idles really rough and when you get that sound out of the tailpipe it jumps like its hiccuping. And tailpipe is vibrating quite a bit.
Things I have done in the past month include replacing the pcv valve, changing spark plugs, cleaning throttle body, cleaning MAF, took down exhaust to check cats because i was experiencing a power loss and bogging. When the exhaust was off i punched the two rear cats. I ran a bottle of iso heat in the gas. Everything seems to have supported the power problem but now less than a week later i am starting to experience the knock and backfire type sounds.

I have a 97 F150 4.6. The truck has developed a slight stumble/misfire when under acceleration. Once at speed it runs fine. It has not given any codes. I've checked for them several times. The plugs and wires have been changed. Is it possible that a coil pack could be bad without throwing a code?

For the past week or so, I've noticed that if my car has been stood for a while (say overnight or whilst at work) I have quite an annoying squeak/squeal when I'm initially accelerating or even coasting within the first couple minutes of driving. If I step on the breaks or speed up, it'll go and most of the time it's then gone for the duration of the drive. Aside from the fact it's highly embarrassing to have everyone stare at my car as I drive away, I'm also extremely worried it's insight into a big problem. What it could be?

I have a 1997 Honda Accord with 193000 miles... I'm trying to decide if I should sell it, as I'm getting concerned about it's future, especially the transmission (automatic). It seems to lurch once in a while, probably between first and second gear. I could sell it now for several thousand (ABS is out). If I keep driving it and the transmission dies, it's worthless, isn't it?. I don't know if the transmission fluid has ever been changed. When I recently got my oil changed, the mechanic said that he would leave it alone if I don't know if it's been changed before. Change the transmission fluid?

I have a 2000 F-150 4x4 with a 5.4 engine. On two different occasions, I have been driving down the highway about 70 miles an hour down a slight grade in OD. When I let off the gas to coast a little the truck will downshift. press on the gas again, the truck goes back into OD. I do this a couple of times and then it wont do it again. What might be happening. Truck has 82,000 miles on it. I am the only owner. Transmission fluid changed a year ago.

I have a 2003 screw 4x2 with the 4.6, 148,000 miles, and I'm not sure what kind of transmission. Recently when the truck would shift into second it would hesitate and I would feel a slight grind, but it only did it when it would shift at 2000 rpm, if it shifted at 2500 rpm it would shift fine. I checked the fluid level, it was full, it smelled okay, looked *fine.
After pulling a boat (19 foot bass boat...nothing too heavy) it started to shake violently when I'd take off from a red light. So I dropped the pan and changed the filter, The fluid was dark red and smelled a little burnt. I put 4qts of fluid in it along with some Lucas transmission fix. The shake during take off is gone, and the grinding while shifting into second got a lot better but didn't go away completely.
However, now the grinding into second has has gotten worse again, and if I make a right turn from a red light it grinds and feels like its slipping until it shifts. I am not sure why making a right turn would affect it but its definitely worse when i turn right, left turns are fine. I'm guessing my transmission is going out and I just need to get it rebuilt...
