Volkswagen Golf 2

07/14/2010 7:46 AM

My golf car has been raising (high) on its own (i mean the engine) even when I am not pressing the accelerator what could be the problem? I have called the mechanic to check on it, he bought a cadburettor cleaner and did some work on the caburretor, yet it does high some time on its own.

Secondly when I start the engine, the engine cranks and roll very well but it takes some time to start some time I use to press the accelerator before it starts, the mechanic said it is the plugs, what do you think?

There is no carburetor, get another mechanic preferable one with automotive training.

Don't press the accelerator when starting unless very cold or flooded and when pressing accelerator hold it to the floor no pumping.

golf is 1990 and its engine size is 1.8, these were fuel injected not carburetted.

I cured this problem by replacing all cables, sensors and the wiring from the firewall forward and removing the CAT...not Del

If you mean that the motor is revving up on its own, check the linkage to the throttle, not forgetting the footplate must be free.

Remove any loose carpets in the foot well of the driver.

Had this problem with our old Golf. We traced it to the throttle cable not sitting correctly at the engine end. Re-seated the cable and the problem went away.

If you have a carburetter on your engine then the butterfly valve in the throat of the carb may be worn on it's spindle and letting air into the manifold when it is shut that would account for the high RPM when idling.

To check if you have play in the spindle, you will need to find where the cable connects to the carb and remove the cable connection Assembly along with the return spring. This will just leave the spindle protruding from the carb body. Then wiggle this spindle in the up and down and side to side to see how far the spindle moves. You will also need to take the air filter off, just to see if the butterfly valve moves freely in the carb body throat.
