Title: problem with cutting out
Post by: dean1973 on 11 October 2003, 14:11

i have a 1996 8v 2.0lt gti anniversary on occasions it will cut out on idle hot or cold. then i restart and all is well.tried earth points cleaning breather hoses etc. have you any ideas???.

thanks volkswizard & vr6 cleaned out the throttle butterfly and check the idle switch(working correctly).its idle's great know 950rpm but and there is a but ,the engine speed is much slower to drop off to idle. now is that right makes for strange gear changes?????.

Look at throttle valve switch/potentiometer. Another common problem seems to be fuel pump/ecu relays.

I have seen this many times on 96 GTI's and it is usually caused by a gummed up throttle butterfly so seeing as this is cheaper than the routes suggested by golfvr6, I'd try it first;

To clean it, disconnect the air intake pipe at the throttle body and you should be able to see the butterfly.

Spray on some carb cleaner or other solvent and wipe off as much gunk as you can.  It helps if you operate the throttle by hand at the same time so you can get to the back of it.

Put it all back together and off you go.  You should now see the revs rise every so slightly as the clutch is depressed and the drop gradually to about 900rpm.

Let us know how you get on.
