throwing at CEL? Could be a bad IACV. or just dirty

924doorEG

no cel at all

yoffer

have you tried adjusting your idle screw located on your throttle body?

924doorEG

yeah and it worked for a while, it idled right, then suddenly it just started going back up again, then i finally turned the idle screw all the way to the right which tighend it all the way and it didnt make a difference

yoffer

have you tried cleaning the iacv? maybe spraying some carb cleaner in the throttle body.

924doorEG

no i havent, should i take the iacv off any spray carb cleaner in it?

yoffer

either that or brake parts cleaner

924doorEG

Sweet, i'll try that thanks alot man, just by the way, any idea on how much a iacv is?

yoffer

If you still have a problem, I would say to check out your ignitor.

924doorEG

ignitor?

cjk95delsolsi

Its located inside your distributor. It is a resistor that connects to you coil and magnetic pickup. Do a search on testing it. I knew it was the problem with my car so I just replaced the whole dizzy.

Okay update, i just replaced the iacv and i just recently like 2 months ago put in a brand new dizzy, any suggestions now?

Have you checked your timing?
