c20let high idle problem
My c20let starts idiling from cold at 1200 rpm and then starts climbing to.near 2000rpm and wont go down I've checked everything. I've noticed its smoking straight away from cold and the wideband is all over the place.The only thing I can think it is is the cts sensor any help would be great its really peeing me off now.
Air leak by sounds of it after throttle body
I've checked for air leaks had all the vac pipes off and boost pipes New gaskets on its got me stumped! I've sprayed around the pipes no change in revs just constantly idling at 2000 rpm.
Any one shed some light !!!
Bttt
electrically disconnect the ICV. If the revs drop it could be an indication its been asked to open (perhaps by CTS failure) if you clamp the hose or block it off and the revs are still high then that would suggest an air leak. The lambda being all over the shop would point towards unmetered air, ie- a leak downstream of the AFM
Ive tried that mate no different being unplugged i did squeeze the icv hose and the revs droppe. Ive now removed the loom and going to go through it for snapped wires so fingers crossed thanks.
Right ive found a few dodgy wires repaired them put loom back in still doing it. I've got another icv to try so will give that a go tonight its really doing my head in now anything else I could check??
Let me no how you get on mate I have the same problem
Will do mate how long has yours bein playing up??
