Title: GTi 16v Engine idle irregular
Post by: allycat on 19 May 2011, 23:08

Hi

Can anyone offer any advise in this are, only at idle after a while the engine almost starts to develop an irregular idle like its missing.

Thinsg i have done:

new leads , spark plugs.
cambelt etc has been done at the same time, could it be the timing thats off.
Replaced the ECU and the 167 relay.

I will clean the stabilizer Valive tonight hopeflly that will resolve the issue but just in cas what else c i check. During the irregular idl the revs saty at a cinatnt 900rpn does not move.  Ihave replaced the airlines to the ecu aswell.

Thanks :smiley:

Could be an air leak.

Hi
I think you right the revs stay at 900rpm at idle so makes it even more confusing for me because you can feel it throughthe seat of your pants when it misses. Will update once i figure out whats going on.
Cheers
