nsawyers 0 Posted June 25, 2006 I have had trouble with high idle with my car since I brought it. The idle screw is all the way in and it sits at 1200 rpm sometimes it drops to 850. I have recently rebuilt the head and changed all thr gaskets hoping to rectify the problem but it is still doing it. The blue sensor has been changed. I was thinking may be the ISV is at fault. Any ideas? plse :mad: Quote Share this post Link to post Share on other sites
G60SC_Stoney 0 Posted June 25, 2006 you can take the ISV off and clean in in carb cleaner, this seems to solve most peoples problems, didnt solve mine though! mine was fixed when i took it down to gwerks to have a few things done to it. you can also just disconnect it (plug on the left side) and that will stop it, just runs a bit lumpy when started from cold for a minute.

Henny 0 Posted June 26, 2006 check the wiring to the idle switch and make sure that the switch is being activated when the throttle pedal isn't pressed. Sounds to me like a dodgy switch problem as the car should idle around 850 RPM and will idle around 1200 to 1500rpm when the switch is disconnected which fits your symptoms nicely... ;) Quote Share this post Link to post Share on other sites
