TrailBlazer :: 2003 Won't Rev Over 3000 - 3500 RPMs Upon Acceleration
Jun 7, 2012
Symptoms- won't rev over 3000-3500 rpm's, upon acceleration (especially uphill) seems to struggle and won't accelerate much at all, seems as if trans changes fine. BTW, throwing no codes at present.
What I have already tried...new air filter, new fuel filter, had cat. check (was told stopped up but when removed found it was not and truck did the same even with cat. off), o2 sensor (upstream) replaced, battery disconnected to reset computer.
After reset of computer, runs a little better but still not good. Seems to start if you accelerate to quickly or when truck reaches around 40-45 mph.

My 1994 Acura Integra makes a buzzing noise exactly between 3000 and 3500 RPMS. It sounds kind of like the sound a circular saw would make cutting wood. It only happens when I am accelerating through that range. Also, sometimes after driving for a while, it doesn't last as long and the noise stops around 3300 RPMS. I've checked the heat shield and it seems to be fine so I don't think its that. What this could be caused by?

I have a 2004 saturn vue. It is a 5 speed standard with a 4 cylinder engine. Now that I have that posted here is my problem. I have normal acceleration up until I hit 3000 rpms. At that point my low engine power light comes on and I lose acceleration. To explain that better, if I take my foot off the gas pedal completely and then try accelerate again nothing happens. My engine stays on but I do not have any reaction when I push on the gas pedal. When I run the computer codes it says it could be my accelerator pedal sensor or my ecm. I do not want to have to replace the ecm if I have to due to how expensive it is.

On highway, at higher speeds (50-70), I notice that the vehicle's acceleration will pause and the rpms will bounce a bit. Best description I can give is that it feels as if someone were constantly pinching and releasing the gas line. Short revvv...revvv...revvv. The vehicle doesn't lose power. I get where I am going. And it only occurs up at these higher speeds.

5 miles to the airport last night, cruising on the freeway, my transmission suddenly accelerates from the steady 3000 rpm to 3500 rpm. When I press on the accelerator, the engine speed and my actual speed are no longer in sync. It feels like the transmission is no longer shifting. The radio cuts out and all the lights dim. My airbag warning light flashes intermittently at me. I make it to the airport, afraid to turn the key off; but I must. I attempt a restart - nothing. All red lights but no engine cranking. What gives? A fuse, the alternator? The car - 2003 mazda protege. The driver - stranded when I return home.

I've got a couple of issues with a 2002, 2.7ltr v6 santa fe first off when taking off steady the car runs fine but taking off quickly it seems to lack power until it hits around 3000-3500rpm est then it takes off fine and all threw the upper rev range the auto seams sluggish but I'm not shore as I haven't driven another 2.7ltr as a benchmark. No error codes are present.
The second issue I brought a new keyless remote for the car and looked up a thread on how to program this they had reference to a set switch behind the fuse box behind the lower dash panel I went looking and found what I think is the remote receiver it has what is like a antenna cable plugged into it but no set-off switch at all is there any way to get this new remote programed or will it have to be done threw dealer or is there something I would be missing?

Car: 1995 Corolla 1.8L automatic
Symptom: misfires around 3000-3500 RPM only when warm.
I have replaced the following:
-Spark plugs, wires, cap, and rotor
-Ignition coil
-Fuel filter
-Poured some quality fuel system cleaner into the gas tank
The car stutters when accelerating in any gear hard enough to reach the engine speed that the misfire occurs at. It doesn't backfire, it just misses... I am confused since so many of the misfire issues I know about that are RPM specific are spark-related.
I have considered cleaning the injectors, but don't want to go through the hassle to remove and have them cleaned unless I really have to. Checking if hunch on the injectors is correct? Something else?

I own a Ford Ranger 2003, 5spd 6 cyl. My problem is when I'm driving and the engine is revving above 3000 rom's. It begins to sputter and buck as if the engine is running out of gas. It only lasts a few seconds. It ends as quickly as it starts. It does not occur each time when driving above 3000 rpms. My mechanic took the truck for a test ride and of course he could not find anything wrong. His advise was to wait until it got worse. I would rather solve the problem now. It is difficult and dangerous when trying to pass vehicles on the road.

Looking for a good diagram of the complete vacuum system on the AEB 1.8t 99 passat. I am throwing a 1136 code which is indicated as a "Manufacturer controlled fuel and air metering". I recently finished a complete rebuild and engine is finally back in but running in limp mode. During the rebuild, I used mobil 1 synthetic as an assembly lube for all internal components including valve train.
I immediately wet fouled O2 sensors and spark plugs. After repeated removal and cleaning for plugs and O2 sensors i have progressed beyond seeing the "wet" fouling but plugs are still very rich, black in color but dry. Engine starts and runs at idle(lumpy) consistently and will run for as much as 5 minutes but very rich. If i rev engine to 3000-3500 rpm it will "POP" or backfire and immediately stall.

When I start my 2003 Escape 3.0, the rpm's shoot up to about 3000rpms. After a few seconds they drop to about 2000 and slowly creep back up to 3000. When I put in gear, I don't even have to step on the gas and my vehicle goes. It maintains between 1500-2000rpms as I'm driving. When I come to a red light or stop sign, it lurches like it wants to go even though I have my foot on the brakes. I've replaced the IAC valve, TPS, had it checked for vacuum leaks, PCV valve replaced. I'm at a loss as to what it could be.

At the beginning December I put my brand new winter tires (general altimax arctics) on the factory steelies and put them on the car gearing up for the snow. Not to long after the install I notice that I was getting a very strong engine vibration starting at 3,000 rpms and it stopped around 3,100 rpms no matter what gear I was in. At first I though it maybe just the cold affecting the engine. Well...
Last week I put my summer rims and tires back on for the 1,600 mile trip to MO and back, and like magic, no more heavy vibrations. Smooth acceleration throughout the normal driving rpm range. I just changed the oil and tranny fluids Tuesday after we got back and with the warmer weather the car is running smooth as silk. Still an awesome car with awesome mileage and couldn't be happier.

I have a '96 Saturn SL with a 1.9 SOHC. I recently removed the engine and transmission to change the clutch. I also changed the timing chain guides, the valve cover gasket, the timing chain gasket, oil pan gasket, front and rear crank seals and motor mounts. After I put it back in, it revs to 3500-4000 rpms and is very rich (so rich it smokes). I replaced the throttle position sensor since it had a crack at the plug and to see if that was the problem. I have looked at everything again and nothing is jumping out at me.

So,I have a mk4 GTI vr6 . I've got an idle that moves about 25 rmps up and down. As well as the throttle hesitation between 2.000 and 3500 rpms only at mid throttle. Has a kinda new maf. That I cleaned. clean THrottle body kinda new coil pack and wires , new plugs. Tried a lot it all worked but it's still there.

Codes currently on ecm: P0134, P2125, P1174, P0735 My 2003 Santa Fe 2wd 3.5l with 160,000 miles was driving fine, then all the sudden whenever I reach about 3500 rpms there's a grinding noise that sounds like its coming from near or in the automatic transmission. As for the codes: P0134- I just replaced the o2 sensor with an oem part from autozone, so not sure why that's popping up. The connections look fine. P2125 and P1174- I'm trying to figure out whether the accelerator position sensor or throttle position sensor needs to be replaced. I have a multimeter but don't know if that will be able to tell me which one is out. The P0735 gear 5 incorrect ratio and grinding noise at 3500 rpms is what I am mostly worried about though. Could a transmission flush work with that?

Just got a 1996 Jeep cherokee with right hand drive, 73,000 miles. Drove it less than 2500 miles when had problems with it shifting out of first gear. Would rev up the rpms to 3500 to 4500 and then a large jolt before going into next gear. Took to transmission specialist who was able to get it to act up., Now he tells me that the transmission is an import??? (was manufactured here in states and sent to Japan) Can't get the codes on the machine to tell him what is wrong with the tranny., says the codes say it is ok. Now what do I do. I need this car as I am a mail carrier and it was bought for that purpose.

I was preparing my sons 2004 escape (3.0L) for a vacation by changing out the spark plugs. When done, I noticed that the engine lacks power during acceleration and has a very high shifting point from normal (3500 rpm). There were no DTC's set so I took it all apart again, this time changing the intake manifold gaskets both upper and lower. I put it all back together and have the same issue. I have double checked (actually quadruple checked) all of the vacuum lines and electronic connections but to no avail. The truck still has very poor power, at idle it bottoms out around 500 rpm. From a start at a stop sign, with the pedal floored it takes a city block to get up to 35 mph. Where I can look next?

Let's say I'm going from zero to forty, my RPMs will hit over 3000, but when it shifts, the RPMS will drop down to 2000-ish really hard, making the car jerk. It's not a smooth drop, it's like a split second. Upon acceleration there is also a very rapid knocking sound. There's no lights on my instrument cluster.
This trouble all started after I had my alternator die, then having the car towed a few months back. Ever since then this problem has been getting worse. Wat this could be?

I own a 2001 Jetta GLX 12v VR6, lately the car has not been running well. It chokes the power past 3500 rpm's and will continue running poorly and sound sort of like a Subaru boxer engine. Sometimes it corrects itself and runs okay but goes back and forth.
I ran the codes on VAG COM:
6 faults found:
17551 - Load calculation cross check
P1143 - 35 - 10 upper limit exceeded - intermittent
16712 - Knock Sensor 1 (g61)
P0328 - 35 - 10 Signal too high - intermittent
[Code] .....
I ran VAG COM a couple of days before these codes came up and I had a different code dealing with air/fuel mixture, something about fuel running to rich. I'm stumped.

So over the last couple of days my GTi has been hesitating as I accelerated past 2500-3500 rpms so I took it in to the dealer this morning to have them look at and sure enough, it had blown an Ignition Coil.
I know this was a common issue with the 1.8l Turbo engines but I thought this had been corrected in the new models.
I have a '10 GTi with 14000 km's on it and some mods (see signature). And no, they didn't comment or ask about the APR chip or intake.

I have a 2001 accent with a 1.6 .... It won't rev over 3000rpm's. It does not have any codes being set. If I unplug the IAC it will rev up just like normal. I tried replacing the IAC, TPS, and swapped ECM and nothing has changed it. I tested continuity of the IAC circuit to ECM and it tests good. Tested ground circuit and it tests good. Have correct voltage at sensor. Not sure what else to look at.

my ac pump kicks on and off no matter what the rpms are at. the ac comes out warm and when i try to charge it the pressure goes up to overcharged and then goes to 0 because it kicks off every 10 seconds.
