Ford F-150 - 1997-2003 :: Engine Revs Up And Stops Accelerating Usually When Shifting Around 30 - 35
Jul 23, 2013
2001 F150 5.4 v8 ... In the past few months my truck has been a bit strange, but in the past few weeks it's gotten to the point I'm nervous to drive it. Usually when shifting around 30-35, the engine revs up and stops accelerating and I have to take my foot off the pedal to make it return to normal. It doesn't do this after I do that, but the past time I tried to drive I couldn't get above 35 and the rpm was in the upper 2000s going at a constant 35. When I stop for any reason such as making a turn, when it shifts it lurches forward and I hear a loud clunk.
Naturally, I've checked all the fluids and fuses and they're all fine. The mechanic I regularly visit insists that nothing is wrong with it.

My Galant is having the above problem. I am providing some details (below) related to the problem: a) Check engine light was on. I took to a repair shop. The code was non specific. They did engine tune-up. The problem was not fixed. b) I took to Mitsubishi. They could not find any specific problem. They recommended changing CAM sensor. After replacement, problem still remains. c) Recently the car doesn't want to start. Check engine light is gone. Revving is still there at start and during stops. d) I have noticed some of the coolant splashing out to the adjacent tubing during driving. The coolant chamber is empty. But the engine heating indicator is in the middle.

Lately I have been driving in the Sport Mode more often. I have noticed that when accelerating from a stop it revs to just below the redline before shifitng, is this normal?
I also notice that when slowing down or coming to a stop, it has a "hurky jurky" feel. As if it was downshifiting way to early. is this normal?

Quick q recently just got a gli and I've noticed a knocking sound when accelerating and shifting from stops could this be my motor mounts ? I was thinking my tranny or clutch but everything runs smooth and goes into gear fine

PCV hose/grommet was rotted out with 1 inch hole but supposedly he spent a long time tracking down the problem. It was located way in the back middle (like underneath the wiper blades area).
2002 F150 XLT Crew Cab 4.6L 4x4 170K
What known issues would do this but not turn engine light on? Motor sounds excellent and runs excellent. Previously it was missing and engine code come up as random misfire, misfire cylinder #2 and #4. I replaced the coil packs on 2 and 4 and erased the code and there was a 1000% difference. Ran excellent (still does).
However, a week later I noticed a subtle shake in the motor, and at idle it would stay at 1...maybe slowly chirp just above 1, and then sputter a little down to 1/2 rpm. It will do this and stay running, but sometimes it will cut off.
What are the possible things that you think it could be considering no check engine codes? (Bad motor?)

2001 F150 5.4 4x4 148K... I recently replaced the intake manifold on this truck and when the engine revs it wants to continue at high RPMs for about 10 seconds after letting off the throttle. When driving, it almost wants to go faster and the gas mileage is really bad. Had some codes come up and took it to AZO and had them checked. P0171 & P0174. Guess I need to do some testing on the MAF and injectors.

I have a 2003 Camry 3.0l v6. Stalls at lights random.
Currently the car stalls at stops but this doesn't happen all the time it can go a month in between the problem occurring its very random. While sitting at a light the rpms drop and then it revs up and cycles like that for quite a while. This will also occur while cruising at a low speed while I'm just coasting the rpms will go up and down. I can compensate while stopped by power braking and keeping it at its normal idling rpm. I have no check engine lights and can't seem to determine what would be causing this issue.

I have got the most aggravating electrical gremlin possible. For over a year now, the truck intermittently just dies. Mostly it happens about 2-3 mins after start (every couple weeks or so), then takes a couple of key offs, then back ons to restart. But it does restart and then runs fine for a time.... 2 weeks ago I was rollin' down the road and hit a pothole, and whammo, she died, and wouldn't restart. I thought, "great it was the intertia cut-off going bad." I had it towed to the shop where they did some diagnosis and told me it threw a PO231 code.
The tech then said he was doing the diagnostic manual directed test, and swapped out the fuel pump relay, and it started right up. New relay, out the door. A few days later on the way to work about 2 - 3 minutes after start, she dies again. I hang my head, say a curse word, and key it a couple times, and it starts back up and runs fine. Presently speaking she's back at the shop, but the owner, who's a straight up dude was loath to take her back, because it was running fine at the time.... I've got to figure this thing out before I drive it off a cliff.
Truck -- 2001 7700 XLT 5.4L 88K miles
Symptoms -- Random interval engine stops with short delay to restart, 1 hard bump engine stop with no restart. PO231 code (after the hard bump no restart). Didn't check it previously (wasn't aware there were "soft" codes).
Troubleshooting to date -- 1 new fuel pump, 1 new fuel pump relay.
Only things left are the inertia cut-off switch (which apparently don't go bad that often), and the wiring itself/connections to the different components....

I have a 98 f-150 4.6L 5spd that has a weird rattling noise coming from what sounds like the engine. The noise will only happen when the truck is in gear and under a load. It will not happen if I keep the RPM's low, unless I am going up a hill. When I rev the truck in neutral, the rattling noise isn't there. Also when I'm driving and hear the ratling noise it will go away when i push the clutch in(which im guessing takes the load off) but will come back when i let out on the clutch. Seems to happen most when I'm in gear and trying to accelerate.

My daughter bought this truck about 6 months ago. This morning a driver cut her off, then hit his breaks. She had to make a panic stop. When she went to take off again, 1st and 2nd was no problem. When she shifted into 3rd, the engine just revved.
She tried to shift back into 2nd, but it wouldn't go into 2nd. She pulled over and now it won't go into any gear. The shifter lever won't even go over far enough to go into 4th, 5th, or reverse. I doubt the panic stop had anything to with it, but thought I'd throw it out there, just because.
Okay here's the truck: 1997 F150, 4x4, base model, short bed, 4.6L, 5 speed manual, manual transfer case, 190k miles. Truck has been beaten and abused badly, but is basically mechanically sound.
Here's what I've done so far. Checked the fluid, it was fine. Pulled the top cover and shifter lever out. I don't have a clue what I was looking for in there, but I hoped to see something obvious. I didn't.

I just got my truck back from the tranny shop 3 days ago,was driving down the hiway looked down and my speedo went from 65 to 0 instantly. it was driving fine till i exited then started reving and not shifting till about 3000 rpms. So i changed the sensor on the rear end and the vss on the transfer case but no results.

1991, F-250, automatic, 150,000 miles, two tanks. Used mostly for towing an RV plus some pleasure. Not in daily use. A month ago I parked it and a few days later cranked it up and found it wouldn't run over thirty MPH. There was some high pitched backfire in the engine compartment and the trans. wouldn't shift. I parked it and the next day it wouldn't start. When I turned the key on the fuel pumps (either tank) ran continuously. Towed to a garage (I am not a Mechanic). They have replaced the fuel pressure control, checked all pressures and it still won't run right. The problem is intermittent. My tranny man said the trans was good. My mechanics don't know what to do. I bought it in 1998.

I haven't come on this site since I sold my Corrado a while back, but I am having issues with the wife's City Golf. It is a manual transmission and when switching gears and accelerating, the engine revs all over the map on the tach and is only partially engaged in gear, and then after bouncing around it settles down drives normal. But if you stomp on the gas again, the engine accelerates all over place again and it doesn't translate to power on the road. Is this a transmission problem or a fuel problem?

2003 f250 4x4 5.4triton automatic. Everything is great except...when accelerating at about 45-50mph & 2000-2200rpms and it shifts into last gear or overdrive. As it changes gears and drops rpm's to about 1500 the engine/trans kind of vibrates or sounds boggish like it doesn't want to push the weight of vehicle or some sort of compression loss? I'm far from being a mechanic. Also, it tends to be more subdued when accelerating harder up to higher speeds, it is more so when leveling out at about 50mph. It doesn't clunk, or grind, or have any other problems shifting except at 45-50 and dropping rpm's.

I have a 97 metro runs good but when accelerating over 70 when you let off engine shuts down for a few seconds then takes off again. Replaced fuel pump and filter to no avail. It must be a fuel problem no misfire.

Car just stopped accelerating on highway. It starts again after about 10 minutes. Also the wheel gets stiff when it stops accelerating. What could be wrong?

I have a 98 F-150 that just went under a trans rebuild. It now will NOT shift from 1st to 2nd. It revs up to 3200rpm's, shifts to 2nd then chirps the tires as it immediately slams back to 1st. Is it possibly a solenoid issue? Looking for some useful info.

I need diagnosing a problem on my 2002 Hyundai Accent LC. When I accelerate with the aircon on the engine stops accelerating at high RPM and when I accelerate from a stand still the engine hesitates and jerks! I don't understand what the problem may be coz it works perfectly after a cold start but after it warms it starts doing that.

I recently purchased a f150 with a reg cab short bed 4.6 4x4, and when you put it in drive the it shifts up to second fine, but when goes to third just revs up doesnt pull at all. Have to shut o.d. off and goes steady but run 2500 rpms to go 40 mph. I was told to check the solenoids but i dont know, if i do need a new trans how do i identify my trans. I know it has the code "U" on the door sticker, but its an 4r70 w code-w. But the junk yard has a YL3P-FA and a YL3P-JA?

So my aunt has a 2002 ford f150 king ranch 5.4l and a night ago it started this problem which when you put it in drive which she has to put it in 2nd for it when she pushs on the pedal it will rev up to 2500rpms than jerks and goes and its usely fine till she stops than goes and it does it again...
Than today it wouldn't even go in anything but reverse... So than we herd about the Range Sensor on the side of the transmission and it seems like it was it so I unplug it when it was running and when i push on the pedal and it revs up to 2500rpms it will go forward and have power. So we went to get a new range sensor after like 4 hours trying to get the dam thing off and another 2 to get it back on.. I started it up and only reverse works again... So I unplug the harness to it again and we got the gears but 1st and 2nd will just rev and go.
We at a lost right now i even tighten the shift screws under the dash cause our expedition was loose at one time and the gear shifter was loose like hers. But even tighten the bolts it still don't fix the looseness or even the gears.. Is this a transmission problem? OR even the torq covertor?
