Question about 1990 Volkswagen Jetta

1990 Volkswagen Jetta GL Accelerator/Throttle sticking

When I first start my car, the pedal is difficult to push down, and when it finally gives, the throttle will not release, causing my car to run about 3k rpm while parked. I've used some JB 80 lubricant on the entire throttle body, but the problem persists. The pedal itself is not the problem, it just dangles loosly while the throttle is on ''full boar''. anyone have any suggestions?

    I forgot to mention, I'm in northern Minnesota, which is running an average temp of 15-20 degrees without a wind chill effect. So if this changes anything, please let me know.

I would replace the accelerator cable. After almost ten years im sure that wire encased by that plastic sheath has a lot of **** in it. Not letting the cable move freely inside of it.

EPC means Electronic Pedal Control. Fly-by-wire for your gas pedal--instead of a mechanical cable that pulls an accelerator linkage on the engine, there's an electronic device on the gas pedal, an electronic device on the throttle body and a wire between them.
You should check the sistem with diagnostic tool.

Two symptoms here Keith, and I just had this, same car year and model. The pedal could either be a bit loose, check the cable and throtle. Have someone check, when the cars in neutral,they manually rev it, and watch the RPM's. They should go 3-4 as normal. If this is the case, and its not the cable or pedal, REPLACE spark plug cables and wires. Odd, but that was the fix to mine. Hope it helps.

Yes it does. But I would clean the throttle body first by taking off the hose that comes from the air filter to the throttle body, held on by a steel clamp. Hold open the throttle plate and spray it down with a brand name carb and choke cleaner. Keep me posted please.

2000 VW Jetta V5 accelerator/idling problem


these cars are fitted with a fly by wire accelerator pedal that is controlled electronically by the cars computer it is possible that there is a computer problem or the throttle body ( air intake system )or accelerator pedal is playing up.
it is highly possible that the car is doing exactly what you say it is i recommend you take it back to VW and demand that they take a proper look at it you might have to leve it with them for a couple of days and get a service advisor to drive it home so as they can see the problem ocure.
regardles the cars computer should of thrown a code declaring a fault in the system witch should give the tecs some were to start looking.

good luck with this problem if you have any outher questions let me no

Hi there, I have a 1990 Volkswagen Jetta Flair 2. I've had the car for about a year now and overall it's been an excellent car for it's age. However, there's always something that needs to be fixed and lately I've had throttle response problems. I do not have any mechanical backround, so I will describe it as best as I can. For one, it seems apparent this is an issue when the engine is cold (or not sitting in the sun all day). I will put the foot down, and it won't respond until it gets to about 3000rpm (right around when I'm thinking about changing gears), and then it rocket ships forward. Before it finally responds, there's a lot of shaking going on in the engine bay. It doesn't sound pleasant either. I took it in for an oil change, and they put fuel injector in it and it seemed to be a temporary solution. Whatever the case, there's a poor connection between me putting the throttle down and the car responding to the action. I do rev it up before I get going, but it's kind of futile. So as a result, I have a tendency to stall in first gear at low speeds as the gas doesn't react when I want it to, and the clutch is usually released by that point. After about 5-10 minutes of constant driving, it will accelerate smoothly. If you can point me in the right direction, whether it's "fuel" related, or it's some sort of heat sensor (I have no idea what I'm talking about), let me know if you've had similar experiences. All my repairs have cost me less than a 100 each time, I want to keep it that way.
