Question: Volkswagen Jetta Stalling
Hi. I read the following article while looking for a solution to a stalling problem I'm having with my 1997 Volkswagen Jetta: 1988 Acura Integra Stalling
This guy's problem sounds exactly the same as mine. My car is doing everything the exact same way. I've taken it to the dealer and had a new ignition coil put on after being told that it was "definitely causing the stall." I drove the car for one day and NOTHING has changed. I know that I need to replace the rear O2 sensor as well as the purge valve. I know relatively little about cars, but from what I've read it seems like I'd be able to change the O2 sensor myself (if that is the culprit).
I've also read that similar problems were experienced from those with a faulty Mass Air Flow sensor, but that wasn't mentioned when checked by either of the two garages I took it to. Could the rear O2 sensor be the problem? Do you have any other suggestions?
Thanks so much,
Gus
Answer:
Well Gus, as I suggested to the person with the Acura, the first step would be to have the system scanned for codes. This will save a lot of time and effort by putting us in the area we need to be to find this problem. With this vehicle you will need a scan tool to get the codes out.
If there are no codes then the advice I gave him still holds, you might have a clogged fuel filter, bad or dirty Idle Air Control Valve and/or throttle body, MAP sensor or a bad Vehicle Speed Sensor.
Question: Dodge 2500 Shifting Problems
Hi Vince, I have a question concerning my 1995 Dodge 2500 series pickup, 4x4, Automatic transmission and 86,000 miles.
Shifting problem: Code #34.
Symptoms:
Usually shifts from 1st to 2nd okay, rpm can reach 3,500 before it will shift into 3rd. 4th and O.D. shift normally. (This is an intermittent problem). Sometime will not shift out of first gear until rpm's are very high. If I use the accelerator gently, it will shift correctly most of the time. If I press down hard on the accelerator, such as shifting into passing gear, it seems to start the shifting problems I just explained. Next time I start the truck it will shift through all gears perfectly. Code #34 still lit.
I don't think it's the transmission that's the problem. I get no slippage and when operating normally, it shifts perfectly. Could it be a sensor?
Thanks,
Jake
Answer:
Code 34 is S/C solenoid circuits - An open or shorted condition detected in the speed control vacuum or vent solenoid circuits. This indicates a malfunction in the cruise control system.
From what you describe, I would have to suspect a bad or sticking governor assembly. To be more detailed I would have to know which transmission you have in the vehicle.
