Tommyd16 Posted February 9, 2015 Share Posted February 9, 2015 I Have a tt auto. In drive everything seems fine but in neutral or park the revs seem to be over just over 1k revs. I can't remember if its always done this or not. My girlfriend pointed it out when we were in the car at the weekend and I can't remember ifs normal or not. When stopped in drive its under 1k rpm In neutral or park it's just over 1k rpm Quote Link to comment Share on other sites More sharing options...
jcbt Posted February 9, 2015 Share Posted February 9, 2015 Try resetting ecu first - have you done anything to the car recently? Quote Link to comment Share on other sites More sharing options...
Poshmalc Posted February 9, 2015 Share Posted February 9, 2015 Probably the idle control valve needs cleaning out mate, mine was doing it too and it's a pain in the ass revving high. Get it cleaned out and you're onto a winner! It'll only get worse if left Quote Link to comment Share on other sites More sharing options...

JackyBoi Posted February 9, 2015 Share Posted February 9, 2015 Mines always idled at like 300rpm is this equally as bad to a high idle?? Quote Link to comment Share on other sites More sharing options...

Ian C Posted February 9, 2015 Share Posted February 9, 2015 Failing that, look for a hose off the manifold, or split. It'll draw in a bit of extra air from that and increase the revs like the throttle is being held slightly open. Quote Link to comment Share on other sites More sharing options...
Tommyd16 Posted February 9, 2015 Author Share Posted February 9, 2015 It idles fine in drive though? Quote Link to comment Share on other sites More sharing options...
Poshmalc Posted February 9, 2015 Share Posted February 9, 2015 For now, you just don't notice it in drive! It's definitely the ICV or as Ian C says a split cam cover breather hose. I cleaned mine and the difference was amazing Quote Link to comment Share on other sites More sharing options...
