Audi - A4 :: 2001 - Won't Accelerate For Short Duration?
Jul 11, 2012
2001 Audi A4 1.8T... Driving down the highway the other day, a lovely place to be stricken w/car problems, the accelerator seemed to just up and quit on me. I went from a solid 70mph to 30, then w/in five seconds it came back to life, thrusting us forward back to speed, then within another five seconds, it cut out and I just made it onto the shoulder. Had it towed home. . . it will crank, but won't start, and now am wondering if it's worth the fix. Dealer just replaced a recalled part and gave me a supermarket list of to-fixes, none of which seem like they directly relate, especially w/out a check engine on or specific error codes. Have replaced the MAF sensor, Vacuum Check Valve, Gas tank/pump, Battery and Alternator w/in the past several years.

My parents have a 08 trailblazer and the brakes stick. basically sometimes you stop and wait at a light or a stop sign, let off the brake and you can feel them stick for about a second and then release. they took it to the dealer, they said they felt it also but dont know what it is. we know its related to the brakes cause they take it there and they say they cleaned up the brakes and then it wont do it for a week or two then it will start doing it again. its still under warr. What it might be?

Maybe it's because I've been away for two weeks and out of the RC, but when I drove for the first time in a while the car seems like it's noticeably bouncy on relatively smooth roads.
Again it could be my break from driving it. I mostly drive on Sport+ mode.

I bought this Escape used in Dec '10 with 29,000 miles. It is now at 36,500 (Sept '11). I have had it in for service 3 times in 3 months.
The passenger airbag seems faulty- if the seat is empty, the light will flip off (meaning airbag is on). If I sit in it, the light will go on and off intermittently. I'm 135 lbs- and the serviceman saw it happen as we drove around- yet when the car was given back to me after a week and a half, they stated they could not duplicate the problem and that no issues were found.
Now, I'm having starting issues. Once over Labor day weekend- I had driven my car, parked it, and went to get in it 5 minutes later- no start. No cranking, no clicking. All lights/radion come on. After sitting for about 20 minutes and attempting to start every couple minutes, it roared to life and was fine. Took in for service, and again- no codes, could not duplicate, so they sent it home.
Car sat for a week (I'm a student- it doesn't get much action except on weekends). Then yesterday, I drove it about 15 minutes, parked, came back 10 minutes later and it wouldn't start again. Again, after about 20 minutes of sitting and attempting to start, it started.

I have about 160K on this truck, head gasket was repaired about 50k ago by former owner, has run pretty well and trouble free since I purchased it four years ago. Recently replaced plugs, coil packs, wires resulting in improved running/mileage. However, I've been getting a secondary air injection system error code for six months or so, (both before and after 'tune up'), performed snorkel modification to prevent uptake of road splashed water, checked fuses next to battery (good). Up to now I just ignored this sole error code since engine was running well. TPS checks 'good.'
Recently the engine would occasionally run poorly for short duration (@ all RPMs & regardless of throttle) and up to now simply parking overnight or just stopping briefly at a store would seem to reset the poor operation. Unfortunately within the last week it now runs like crap all the time: over revs for upshift, poor power, almost feels as if a cylinder is missing entirely, or timing has gone horribly 'off.' No other error codes, no obvious vacuum leaks. Ran through two bottles of Techron, no change. Does the 'toggling' of the engine running poorly/well offer any clues? Sticky injector?

My 1995 Audi 90 Sport needs to have the acceleration pedal pushed very far, about half way, before the car begins to to move, also when the pedal is put all the way to the floor the vehicle only goes to around 70mph. And finally I am having trouble finding a shop book for the vehicle.

'01 A6 2.7T 95k....Not boosting as high as normal...the check engine light came on the other day, P1136 code said engine was running lean. I found a small vacuum hose leak near wastegate and fixed it today (CEL is still on though). Stock boost is normally around 8-9 psi, but I am only getting 6-7 psi. Also, the boost seems to climb more slowly than it has been, and it occasionally goes into limp mode (only 3-4 psi). The turbos were replaced about a year ago with all new blue hoses. There aren't any other symptoms, no weird noises.

My daughter just had a new front tire put on her Audi A6 AWD, 2001 car and now her traction control will not turn on. I've been told that being it is all wheel drive that the tires need to have the same wear and that all tire will need to be replaced to prevent damage.

I have a 2001 Audi TT, every time when I push the gas pedal down the car is shaking(not whole lot). I replaced one of the injection coils but still does the same thing.

'01 A6 with 95k....I have noticed intermittent hard turning to the right at low speeds.. Only to the right though, turning left is fine. It feels like there is no power steering, then all the sudden it will start working. It does NOT seem to be temperature related. Usually it clears up after a few minutes of driving, but it has gotten worse. Does this mean the whole rack needs to be replaced? Would flushing the fluid support at all?

I have a 2001 Audi A4 1.8t (AWM engine, B5 platform). When I start the car, I get misfires on all cylinders (very rough idle, sometimes it stalls when the engine is cold) and the car appears to be running lean. Once the CEL comes on, it runs fine (albeit the slight loss of power do the ECU going into limp mode to correct the problem).
So far, I've done the following myself: new O2 sensors, new SAI pump, new EGR valve, new diverter valve, new N75 valve, new vacuum hoses, cleaned the throttle body, new MAF sensor, cleaned the air filter, new plugs, and new coils. When the problem persisted, I had my mechanic change the timing belt, check for vacuum leaks, change the valve cover gasket, replace the fuel pump and filter. None of this has solved the problem! This is driving me nuts.
At this point, there are only two possibilities that I can think of:
1) Catalytic converter is clogged? I pulled out the pre-cat O2 sensor, started the car, but it still misfired. This seems to mean that there's another problem (i.e., if the cat is clogged, it's in addition to something else).
2) Dirty fuel injectors? I've put two bottles of Techron through the car to no avail. From the outside, they look pretty dirty, so I'll definitely try removing them, cleaning them, and replacing the gaskets. Hopefully this solves it.
Is there something I'm missing?

2003 PT Cruiser won't start immediately after short trip with a short stop. Always does start after turning the key and holding it to start position. The check engine light is often on and the code is for a cam shaft sensor or resistor sensor. A companion problem is the cruise control. If the check engine light is OFF and I use the cruise control, it works fine for a while and then the check engine light comes on at the same instant the cruise control turns off. Are these 2 issues connected? How much should it cost to have the sensor replaced? The car always stays running once it starts and the problem occurs randomly. What are the consequences of not repairing it?

In the summer months when the air conditioning is in use, there is a back up of water. i can hear the water sloshing sound when the air is on and when making sharp turns it actually drains out on the front floor, both driver and passenger sides. it has also overflowed out the backseat air vents. my mechanic has told me the drain on this vehicle is tiny and becomes clogged easily. the car is parked in my garage, not left out in the elements so i disagree.

My car dealer said that I must change oil in 5000 km or 6 months. My car didn't exceed the 5000 km yet. But last oil change was 8 months ago . Should I change oil after 5000 km.

I have a 2001 Suburban 2500 4WD. When driving over any bumps, the gauges go to 0 (all gauges, speedo, tech, fuel, temp,etc.) and the battery, abs, and airbag lights come on. It is just an intermittent problem. Everything immediately comes back up until the next bump.
Note: nothing else is compromised (headlights, radio, performance, etc. are not affected)
I have taken the cluster out and "bounced" it around in my hand while the truck is running and cannot duplicate the problem. I have check ground wires and battery cables.

I have a strange problem with my 2001 Santa Fe GLS that I can't put a finger on.
With my AC running, whenever the condenser fan (the one on the driver side) comes on, the electrical system seems to short out briefly (1/2 sec) - all lights go dimmed, the vehicle bucks - very scary when driving. Sometimes the engine sometimes shut off if idling.
I've changed the AC compressor (twice) and changed the entire condenser fan assembly to no avail.

We are at 120K miles. The vehicle runs fine most of the time, but every once in 10-15 starts, it will rough idle or stall after a short warm up time when my wife stops at an intersection. Once she restarts it, it runs fine.
I have changed the spark plugs and wires, the fuel pump, the crankshaft position sensor (was fried) and after consulting this forum, I checked the fuel pressure regulator and the diaphragm is not leaking.
I was able to recreate the rough idle and the CEL on the dash, but my two OBDII readers said there were no codes And the bluetooth reader I am using is indicating that the following tests are not completing: Fuel System, Catalyst, Evaporative System and Oxygen Senors.
The dash CEL resets itself upon restart and does not light until the symptoms return.
After reading the Haynes Repair Manual, I am wondering about the Evaporative Emissions Control (EVAP) system? But I don't want to lead the troubleshooting.
We bought the vehicle at 60K miles and it has been mostly reliable.

I have an issue for the last couple of years. I drive a 2006 hyundai santa fe with 168,000 km's on it. the problem I am having only happens on any cold day and never above zero celcius and when I start the vehicle on a cold day and go for a short trip to the store run in for about 5-10 minutes and I come back out and it won't start, there is lots of power but it wont roll over at all but after trying many times it will eventually start and there is no CEL showing and I have never plugged it in on a cold day and as cold as the canadian winters get here its been down to as low as -40 in the morning and no problems at all, a little roll and a groan and away she goes which is typical in our cold climates.

My problem is similar to that of coyote54 back in 05. I have a 2001 Grand Caravan Sport. Instrument Cluster is dead, Information lights on top of dash are dead, Turn signals and Hazard lamps are not working. Found Hazard Lamp fuse to be blown. Replaced fuse and blows immediately indicating a short. Haynes describes a Turn Signal/Hazard Lamp and Daytime Running Light Module located on the junction block but there is no such animal that I can find. One of the responses to coyote54 described a Hazard relay located within the steering column........again, I do not see anything on the column that resembles a relay. Is there a hazard flasher/relay on the 2001 GC.

I have an automatic 2000 Volvo S70 with 202,000 miles. Over the past couple years, I've had an intermittent start problem that seems to only occur after a medium duration shutdown (15min-3hours) following a long duration of operation (about 2 hours or more, usually highway). When the problem occurs, all the lights on the dashboard light-up like everything is normal, but when I turn the key to the start position, nothing happens - silence, the car makes no attempt to start. Usually, I'll wait anywhere from 3 minutes to an hour or more and it'll start with no problem, like there was never a problem in the first place.
It seems to happen more frequently when it's hot outside, but it's hard to say for sure. And it seems to be random, within the parameters previously described; example: it happened twice on my recent drive to vacation, but not at all on the return trip home. Both days were hot, and all stops followed a similar pattern of operation/shutdown. And it never happens after a short stop following long operation; I've never been stuck in front of a gas pump. And I can run errands all day long, stop a dozen times in the blazing heat, and she'll start every time without a problem. It never happens first thing in the morning, and it never happens after I've been at work all day (even if the car has been parked in the sun all day).

This concerns a 2003 Hyundai Santa Fe 2.7L engine.
Bad rain, combined with a puddle splash caused a short (someplace). Vehicle ran poorly on way home and then eventually failed to start. Replaced the Cam Position Sensor and the Crankshaft Position Sensor. Checked all wiring and connections. Cleared codes and the vehicle started. Ran for about 15/20 minutes and a P0340 code popped with the engine light on. Car still runs fine. Researched code and learned that this code is a Camshaft Position Sensor A - Circuit Malfunction.
1. Bad ground in Circuit.
2. Open Circuit that fails to close.
3. PCM malfunction.
Questions:
1. Where in this vehicles is the PCM located? Is it within the main ECU in one of the other ECU fuses or an independent fuse?
2. Other than the 3 issues listed above, could I be overlooking anything else?
