I drive a jdm h22a hatch and on start up the car idles at around 1100rpm. I drive down the road and hit a stop and it idles at 1500rpm. Also have a skunk2 68mm tb with the stock manifold. Tried messing with the idle screw but can't make the idle drop at all. The vacuum lines were all replaced. Could I move the tps sensor a bit? Any suggestions?

 

usually when adjusting idle, you unplug the iacv then turn the idle screw down. reset the ecu and it should be good.

you could also have air in your coolant system. could always try bleeding the sysytem.

 

yeah i tried taking the iacv plug out and from what i heard your suppose to get the rpm steady at 2k and then turn the screw but nothing worked.

 

what you do is turn the car on, unplug the iacv connector, then turn the screw down so the idle is sitting at desired rpm(usually 750rpm). then plug the iacv back in. reset the ecu.

 

Sounds basically like a non issue to me. 1500 RPM's is a okay idling point. If it's not broken don't fix it...

 

I did that but the idle doesnt drop as a turn the screw inwards

 

*edit*

maybe you have a leak between the IM and TB. check for leaks by spraying water or brake clean. if there's a leak, there should be a slight surge in your idle.

 

no i have a NEW skunk2 tb but its been running at this idle for a while. Could it be the throttle body gasket?

that's what he said. Spray some carb cleaner and see what happens
