Thread: high idle question

Ok my car is idleing around 1500rpm, it idles at about 1100cold and 1500warm, i have the iacv screw all the way in and it doesnt change, im wondering if the when i pinch the hose for the AAC and the car dies, if the AAC is stuck open and not restricting like it should ? what do you guys/gals think

Might want to check your timing also. If that is to retarted that will cause you to have a higher idle even with the screw all the way in. I take it this is on the 98 SE?

this on my NX2k, the timing is almost dead on at 15 degrees

I thought it was the other way around, advanced timing raises the idle

the tps is at .48 timing is almost dead on, no vaccum leaks that i can find, im thinking the AAC is just stuck open

What ecu are you using?

it is a basic calum for 72lb and Z32 mafs

Well I know mine did it both retarded and advanced. That's how I found out my IACV went bad.

pull the iacv apart and clean it
