Suprash Posted March 20, 2011 Share Posted March 20, 2011 Dunno but I have the same on my NA-T, its currently idling around 1800-2000rpm I think, I havent yet figured this out Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted March 20, 2011 Author Share Posted March 20, 2011 Damn, really annoyed because it was at 1200rpm before cleaning the icv and now the the icv is clean its gone upto 2200rpm and just doesnt feel as nice to drive, doesnt make sense wish i just left it alone now Quote Link to comment Share on other sites More sharing options...
FOSTA Posted March 20, 2011 Share Posted March 20, 2011 hi guys iim no expert but have you guys had alook at your butterflys in the throttle? just as im sure i heard somewhere that they get a build up with crap over the years and become abit sicky! so i might be worth a quick check and a clean with abit carb cleaner! also check vacume all tho i think i leak my lower revs not raise them but like i said im no expert! hope this was some help to yous! and i hope you guys find out the problem! as there is nowt worse than a fault you just cant pin point!

Swampy442 Posted March 20, 2011 Share Posted March 20, 2011 Throttle butterfly, check all the vac lines on the inlet for air leaks as well Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted March 20, 2011 Author Share Posted March 20, 2011 Ok cheers will do, i think it must be something to do with the icv though as its only started idling at 2200rpm after i took it off cleaned it up with brake cleaner and put it back on about 20 mins later Quote Link to comment Share on other sites More sharing options...

Parry_10 Posted March 20, 2011 Author Share Posted March 20, 2011 Ill have a look at that mate mine is a tt though so not sure where that is and it used to idle ok so i doubt it is that Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted March 20, 2011 Author Share Posted March 20, 2011 just noticed i must of knocked the pipe off at the back of the inlet manifold put it back in and its back to how it was idling at around 1200-1300rpm, so cleaning the icv and resetting the battery has made no difference also I have just fitted a new o2 sensor I am getting fuel cut at 5000rpm now and it must be because of the high idle as when I got my car dynoed by ryan it was fine he set up the fcd and it didnt hit fuel cut at all Quote Link to comment Share on other sites More sharing options...

Suprash Posted March 20, 2011 Share Posted March 20, 2011 Throttle butterfly, check all the vac lines on the inlet for air leaks as well Already been over all my vac lines.... This was my problem http://www.mkivsupra.net/vbb/showthread.php?240395-Whats-this-(with-picture) reconnected it and its sorted now. check yours is still connected, (the rod) Pretty sure I checked this other day and it was good but now you have me thinking lol... just noticed i must of knocked the pipe off at the back of the inlet manifold put it back in and its back to how it was idling at around 1200-1300rpm, so cleaning the icv and resetting the battery has made no difference also I have just fitted a new o2 sensor I am getting fuel cut at 5000rpm now and it must be because of the high idle as when I got my car dynoed by ryan it was fine he set up the fcd and it didnt hit fuel cut at all So you fitted a new O2 sensor and since then you're getting fuel cut ? Why do you say this has to be from the high idle then ? Have you maybe tried swapping back to your original O2 sensor in case the new is duff........meister Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted March 20, 2011 Author Share Posted March 20, 2011 the idle was high anyway before i fitted the new o2 sensor... just dont know whats causing it really starting to frustrate me now Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted March 20, 2011 Share Posted March 20, 2011 The throttle butterfyl? Throttle cable tension too high? TPS problems? Quote Link to comment Share on other sites More sharing options...
