Question about 1998 Volkswagen Jetta

1 Answer

Sluggish response to acceleration and engine randomly shutting of

This has occurred to me more than once and always after I have not driven the car regularly after a few days (I'm in the military and spend a lot of time in the field).  In the past I was able to solve the problem using water removal fuel treatment and fuel system cleaners to my gas but that isn't working now.  So far I have replaced an oxygen sensor, mass air flow sensor, ignition coil, spark plugs and wires, found a short on a ground wire, and tightened the boot around the throttle.  Everyone I have taken this too has treated this like an electrical problem because of a misfire code that was coming up (occasionally appears but just shuts off on its own) but it does not feel like an electrical problem at all...more like a fuel problem.

Do you usually purchase your fuel at the same station? Sometimes stations have issues with old tanks in the ground that accumulate condensation from old age and or the fuel that is delivered to that station is sub standard for one reason or another. I dont like to assume anything but maybe check around if anyone else has had an issue with stations in your area. Make sure the ground wire that you repaired was fastened on properly on BOTH ENDS of the wire or wiring harness. Did you do a full tune up on your car? Air filter, fuel filter, all the plugs and ALL the wires, Distributor cap and rotor? Have your air flow meter tested to make sure its operating properly. Sometimes if you use to many fuel additives in your engine over time, it can lead to the spark plugs burning to hot and shorten the life span of the plugs. Do you live in a humid environment and if so, you could be collecting moisture in your distributor because of how long the car sits in between use. Sometimes heavy rain and then the sun creating humid conditions, can lead to this problem when the car isnt used on a daily basis. Also make sure that when your airflow sensor was replaced that it was connected securely without any moisture or corrosion on the contact points. Hope you find this helpful or at least leads you toward the right direction.

Why does my 2000 camaro 3.8 have a random surge during acceleration when the Asr is turned on?


ASR is your traction control, the reason why you have a surge is that the ASR is calculating how much force to give to each tire based on sensor data, and this takes time. When you turn it off, the acceleration is treated like any other car with out traction control. The 2000-2003 Camaro had one big complaint, a laggy traction control. You could potentially fix this by replacing the computer unit with a faster aftermarket model and changing sensors out with more efficient models, also tuning the engine can help reduce lag time or acceleration delay.

run fault codes as it may be the accelerator position sensor Check the cat converter for failure that is blocking the exhaust pipe.

Hestitation almost to the point of stalling


I would focus on fuel delivery including fuel pressure. Any of the sensors would turn the check engine light on, but low fuel pressure would not. Fuel filter, problem with a line going to the tank, debris inside the tank blocking the pump, etc.

you know what that sounds like it may be.... believe it or not check your trans fluid (car running WARM and in park ) make sure that the fluid is red almost pink like not dark red. Also why not try and change out the spark plugs and air cleaner!

2003 ford f 150 4.6 v8 and the idle went from smooth to rough also sputters and sluggish while driving check engine light is flashing.


have the vehicle scanned for error codes at autozone, its free. Post codes for more help....These engines have issues with the COPs (ignition coils-over-plugs) failing prior to 80k miles. When they fail typical problems are: Sputtering under load/acceleration, rough idle, random misfires, random stalling, light or heavy jerking under load (usually at 15-35mph and 45-65mph)..hopefully this helps!!

Zero throttle response and sluggish accelertation


Wow, great description...I suspect the catalyst is bad...(in the exhaust) but try this cheap fix.
go to Advance Auto Parts and buy a can of "SeaFoam" ($8) and following the directions add to fuel and drive for at least 100 miles...see if that helps...if not, have a mechanic look at the catalytic convertor/exhaust
Good Luck

Momentarily Sluggish Acceleration


Are you loosing power to the ecu when the car is shut down? most cars with an ECU that controls timing, fuel, or boost can be forced to relearn the car if the ECU looses power (called a "limp" mode). I'd look into this. Also are you getting any check engine lights? considering the description of the problem, this would help to diagnose. Try getting the car started and running normally, then turn the car off but do not kill the power to the car, just stop the motor from running...Fire the engine back up and try to give the car a good stomp on the gas and see if you get the same sluggish problems...my 2 cents... Good luck future auto DIY's

'99 Chevy Cavalier


If this only happened AFTER you drove through the water, I'd say it had to do with the water. When ignition parts get wet, they short out and lose performance. Once they heat up and dry out, they will be back to normal. If you haven't had a tune-up in a while, I suggest you get one. Ignition wires are usually the first to give you problems when they get wet. Sometimes if it's really damp outside, you can have the same issue you did when you drove through the water.
