Golf GTI revs - tonyh
My son has bought a Golf GTI 1991 with digifant fuel injection.When it is returning back to idle the revs drop below normal for a moment sometimes causing it to stall, any tips or clues on how we can remedy this please thanks tonyh

Clean out the idle control valve with carb cleaner.

............and the throttle disc and venturi. If the oil is really old and fumy this won't help either.

Check the idle valve or the throttle valve switch. I had a similiar problem on a passat a couple of years ago and it turned out to be the throttle valve switch.

Many thanks for the very helpfull replies, we cleaned the I.S.C.V,throttle body and the idle jet [it was covered in a tar like substance] and the car is now performing OK tonyh
