Passat (B5) :: 1997 - Heat Only Works While Accelerating
97 passat vr6. I only get warm air from the vents when I'm accelerating. As soon as I come to a stop it starts blowing cold air. Does this mean there is air in the system? If so how do I bleed it out?
View 1 RepliesPassat - Volkswagen :: 1997 - Feels Like Downshifting Even When Not Accelerating?
When I'm driving, steady mph, my car feels as if I've just downshifted, or that my foot slipped off the gas pedal. When this happens I've noticed that the tachometer drops down from say 20 - 30 to 10 or less! But just momentarily. It happens to a warm or cold engine. It's going to give me a whiplash! I've brought it to my VW dealer. They put it on the computer, and no problem comes up! No lights on my dashboard are on either. This problem is really annoying.

I have a 1997 GMC Sierra extended cab with auto trans and 5.7 engine.When accelerating it bucks like it is underpowered. If I manually downshift to 3rd it runs fine. Once up to speed, I manually shift back to OD and it runs fine.

My 97 Explorer 4.0 SOHC has started to bog down when I press the accelerator. It feels like their is interference with the exhaust. I has a new muffler and there are no holes in the exhaust system. When I stop at a light or in traffic, it will stall. I have to keep the RPMs at 1000 while holding the brake. There is no check engine light on. Where I should begin to look?

My Grand Am has a bad oil leak (timing chain gasket) recently overheating and now makes a knocking noise while accelerating, especially up hills - which stinks as I live in Pennsylvania! I am pulling it apart - camshaft covers (both - its a dohc) and timing chain cover. How do I determine if its a main bearing or bent lifter rod or bad rockers?

Ive got a 2000 4x4 F-150 with a 4.6 and a 4r70w. The transmission and transfercase were replaced by the P.O aprox 2,000 miles before i bought it..
i was driving it today, and while accelerating it missed a shift into 3rd, then nothing no forward or reverse, i sat and messed with the gears for a while then suddenly it shifted into 1st now it drives with a slight resistance, revs up to about 3K before shifting and shifts HARD up and down, and i cannot get over 40 mph its at about 2800 rpms and feels like im hitting a rev limiter wont shift again and wont accelerate anymore..
When at that speed I hit the OD off and it downshifts so i think i still have od?
Ford F-150 - 1997-2003 :: Bogs Down And Stumbles When Accelerating
2002 F-150 4.2L. About a year ago, it threw the P0171 and 0174 codes up. After replacing all the simple stuff, I bit the bullet and replaced the lower intake gasket as well as the upper intake gaskets. Buttoned it all up, reset the codes and we were back in business. No issues, truck ran good. About 6-8 months later, the check engine light came back on, I check it and it was that pesky set of codes again, 0171 and 0174.
It still ran fine, but the codes were there, so I just drove it for a while (it's a company truck that doesn't get driven that much).
A couple of weeks ago while driving it, it acted very sluggish. You could mash the accelerator and it would just very slowly run up the speed. It never hesitated or missed, it just got very very sluggish. Checked the codes, no additional codes.
Then it began to stumble when you mashed the gas.
I put new plugs (old one's looked great, other than a huge gap), new wires, new coil pack and started it. Pushed the gas pedal, it just dies.
I look for obvious vacuum leaks and replace a couple of elbows for the PCV and it seems to run a little better. Enough so that I can drive it, but still not running right.
I ordered all the intake gaskets and new isolator bolts and spend Saturday pulling that apart. I didn't do the lower intake because the upper intake gaskets looked so good, I just don't believe this is a intake gasket problem. None the less, I installed the new gaskets on the plenum and upper intake, new isolator bolts, replaced a couple pieces of vacuum hose that looked cracked, started it back up, it ran as smooth as silk.
Convinced I had it fixed, I went for a test drive. Idling, it is as smooth as you could ask for. Pull up to a stop sign, wait, step on the gas and it chokes. Just stumbles and you can hear it almost backfiring and pushing air back through the system.
I've put new PCV, new EGR, new vacuum lines in several places, new upper intake gaskets, new plenum gaskets, new isolator bolts, and even new o-rings on the injectors, and I'm still getting the 0171 and 0174 codes.
With the diagnostics on, I can see voltage varying on all O2 sensors, so I assume they are working (none of them are reading 0 volts). It doesn't throw any other code up, other than the 0171 and 0174.
At this point I feel like I'm replaced every single thing ever mentioned in any 0171 and 0174 thread on the internet. Where to go next? 1 more point, if you very slowly push the gas, it runs fine, but any pressure on it, it bogs down and just stumbles.
Ford F-150 - 1997-2003 :: Transmission Hesitating While Accelerating?
Recently, my truck has started rolling back from a stop when accelerating. There seems to be a hesitation between when I depress the throttle and the transmission engaging. It doesn't clunk, just delays. Been doing it for a few weeks, but is now getting worse. Today, the symptoms are similar but more pronounced. When driving there doesn't seem to be an issue, just moving out from a stop.
Checked the fluid idling in park, level was good, fluid looks great, was changed by a shop 6 months ago. Is my 319,000km trans on its way out?
Ford F-150 - 1997-2003 :: Shake / Shudder When Accelerating Around 45 - 55 MPH
My trucks been doing something weird. When accelerating around 45-55 mph, a couple seconds after it shifts to 3rd, it does a weird type off shake/shudder. Feels like I hit a small bump in the road. Also when coming out of a cruise to accelerate, it will Make a very violent clunk and then speed up. I'm thinking it's a problem with my torque converter but my mechanic says transmission and my buddy says rear end lol. I dropped the pan and there was some shavings but nothing huge and it was the first time it was ever dropped. After 90k miles.

So I have an issue with my 03 f150, Basically It clunks in various scenarios such as Accelerating also occurs take off and general breaking/slowing down but not really when stopping. December when it was cold and I was decelerating (not on the break just coasting) it feels like i was driving on the shoulder.
It does it much more in cold weather. Just had the truck out getting a little rough with it for 5 or so hours today and 0 issues with it.
I was thinking it was a slip yoke issue that I hear allot of trucks have the issue but I was at the dealership today and both guys and a mechanic sitting there were like "never had that issue on an 03 f150, might be your back end." They also stated the clunking would always occur and be more prominent when breaking which its not.
I am certain its not the transmission its not occurring with any shift point. Kind of hard to do it if its hard to reproduce in the heat.
Ford F-150 - 1997-2003 :: Humming Noise While Accelerating?
Noticed the other day when I was driving on the highway my truck started humming when I was accelerating past 30. From a dead stop to 30 its fine, but after it starts humming. Its only when I have my foot on the pedal. When I let off, it stops. The sound is coming from the rear/under.

Just purchased a 2001 Ford F150 super crew lariat v8 4.6/5.4 2v OAD at 156k miles, iv had no problems with it until I drove over the pass and after 2hours of driving my truck started to jerk when I accelerate between about 40-60mph. I don't experience any other problems over 60 it runs smoothly and in town under 40 it also runs smoothly, no check engine light. The next day is still continues to make a jerking motion, which feels like from the rear.

I have a 2001 F150XLT 4x4, V8 Triton engine with offroad package that just rolled over 119,000 miles that just started giving me problems 2 weeks ago. When I accelerate at speeds above 40 mph the truck surges or jerks ( the best way i can describe it ) sporadically unitil I get to cruising speed. If I'm cruising at say 70 mph and go to pass some one and accelerate it does it again. The transmission feels like it shifts smoothly thru all the gears and there is no whining sounds, transmission sounds normal. There is no check engine light, so I assume a diagnostic check might not show anything. Advice from guys at work say possible ignition module, coil pack, transfer case ??? It never feels like the truck wants to stall and it never feels sluggish when accelerating like there is a fuel problem.
View 14 RepliesDodge - Ram - 1500 :: 1997 - Idle Roughly At Warm / Accelerating
I have a 1997 dodge ram 1500 4x4 with the 318ci engine. 140,000 miles. Fall 2009 I replaced the CAT (old one had broken loose and was rattling around inside) and both o2 sensors. A few months later, when I'd start the truck cold it would idle fine then as it warmed at idle it would run rough almost quit then idle up and run fine all by itself. When started warm it would idle fine then hesitate while acclerating a few times then run fine. No check engine light. Now, about 10 months later check engine light is on (P0138 o2 circuit high voltage bank 1 sensor 2). I have put about 5,000 miles on the new CAT. I checked the wires and connections for damage and found none. Also, new cap,rotor,plugs and wires.
View 3 RepliesToyota - Rav4 :: 1997 - Hesitates Between 1500 - 2100 Rpm While Accelerating
I recently purchased a 1997 Rav4 (3F-SE Engine) with 162000 miles. Overall, it is a great car. The only problem (besides a clutch, which can wait) is that it hesitates/bucks between 1500-2100 rpm while accelerating. This happens usually on a shift change from 1st to 2nd, or while in 2nd and after decelerating to make a turn. This only happens after the engine has warmed up, i.e. the temp gauge is above 25%. When cold, there is no hesitation at all. It just passed emissions testing. Check engine light is off. I recently replaced the TPS (and adjusted it properly), with no change in symptoms. This car does not have a MAF sensor.

View 5 RepliesFord F-150 - 1997-2003 :: Truck Shakes When Accelerating Hard
Its not the tires/wheels. I just had them balanced. It only shakes when hard accelerating. If I am easy on it, then smooth as can be. It gets worse with the RPM of the engine. I am thinking its in the tranny.
It still shifts smooth and I have been pulling 17 mpg on the interstate with it. So I know its acting correctly? Could I have blown something in the trans or ballooned the torque converter?
It just started the other day, I drove about 350 miles on vacation and noticed it when I went to come home. Like i said it only shakes when you lay in to the throttle, and it gets kinda violent.
Ford F-150 - 1997-2003 :: Truck Developed Stutter When Accelerating
I have a 1997 Ford F-150 XLT 4.6L 4x4 Auto and it's having an issue. My truck has recently developed a stutter when accelerating. It feels like a serious misfire and actually pulled a code for a misfire on cylinder 7 (although I haven't been able to get the code to appear again). The plugs are pretty new, I think I only have around 10k miles on them so i figured it might be the coil pack. I bought 2 new coil packs but only one was in stock so i replaced it on the drivers side bank (which controls cylinder 7) and it didn't fix my problem. When I first start the truck and drive it, it isn't very noticeable, but as I drive the truck for a few minutes, the stutter gets more violent. I will replace the other coil pack tomorrow, but I have my doubts it's the problem. It acts just like a bad coil pack.
View 9 RepliesFord F-150 - 1997-2003 :: 2002 - Bucking Whilst Accelerating?
I have 2002 4.2L F150 w/ Manual Transmission. The problem I have started about a week ago. I noticed it started to idle very rough and at times felt like it would almost stall if i didn't keep giving it some gas. Then a few days later it started to jerk/and buck intermittently while accelerating. I changed out the plugs and wires. My coil pack was replaced a year ago but was still under warranty so i installed a new one just in case. I cleaned and inspected the EGR valve and replaced the TPS. The rough idling seems to have cleared up but the jerking/and bucking still remains.
When the engine is cold the truck runs fine, and then as the engine starts to warm up it will jerk and buck while accelerating at any speed. Once the engine has reached its optimal temperature the jerking/bucking goes away and it runs smooth as silk. I can drive it for for a few hours with no issues whatsoever. As soon as the engine cools, the cycle starts all over again. I figured maybe the intake gaskets were on their last legs and when they heat up they seal tighter causing the engine to smooth out.
So I replaced the upper and lower plenum gaskets today and cleaned everything up. It still did not fix the problem.
