[Justice Ivan]

mk1 golf gti idling at 3200 rpm. anyone no the answer?

Possibly the idle control valve, or throttle linkage not returning to the correct position. (sticking cable or mechanism)

My MK2 did something similar but lower down. Adjust the inlet manifold so it rests correctly just under 1000rpm

You can reset the throttle position on these but you will need the software to do it

On a MK1?

Hmmm some interesting replies here.

Anyway, first stop is the idle control screw on the back on the manifold. From memory if that falls out (as it did on mine) it will idle about 3,200rpm so that sounds the first place to look. It is a brass screw that should be thread-locked into the manifold - it is a bugger to do as you can't see it and have to feel round the back. Easiest thing to do is use a mirror or feel around there and if you feel air being sucked in then that's the job.

Failing that and you want to give lots more details then ask here http://www.vwgolfmk1.org.uk/modules.php?name=Forum...
