Iac valve question
Well My IAC valve has been acting up latly the truck idles real high.
The auto parts store wants $80 for a new one, But I foung that if I unplug the wires runing to it the problem stops and the truck idles normal.
My question is if I keep it unpluged will it cause problems with anything else?

I left mine unplugged for a few days, and all i got was a check engine light(im actually thinking about unplugging it again).... i wonder if you could connect the wires going to the IAC to keep the check engine light off.....probably not though.

I tried cleaning my IAC a couple of months ago with WD-40 & a foam swab, so far so good. (don't use a cotton swab, it's linty)
Mine was sticking where the plunger shaft goes through the shiney metal disc, into the electromagnet end. There were carbon deposits on the shaft, causing it to hang up.
Don't know long the cleaning will last, but I see one poster has had good luck for two years now, thats pretty danged good & certainly worth a cleaning try imo.

Unless you have a vacuum leak, it should not idle cold w/ the iac unplugged.
My experience w/ cleaning them is that they only last for a short time after that before they start to stick again, so once you clean it and confirm that was the problem, then I'd recommend replacing it.
