im having idle problems too, at start up the idle struggles, and when im rolling the idle sometimes drops down to 0 and even stalls the car, sometimes the idle will shoot up to 1500-1800 and come back down. After a bit of driving it stabilizes. Gonna have a look at the iacv hopefully wont be too hot to work on it. Give you a update when I can.

Check the IACV. It might also be an electrical issue. Jiggle the wires around the engine bay and see if the idle changes.

Thanks guys i jiggled the wire a little tonight for the Mass air flow and the idle changed gonna mess with it some more tomorrow i also might spray the iacv with carb cleaner.

I learned of a quicker way to clean the iacv without taking the whole thing off (of course....this is after i took the whole thing apart)

You can try just by taking out the idle screw, and shoot some cleaner in there...then re install screw...reset idle....done

Im not gonna take it apart as this is my only car right no im just gonna shoot cleaner down the hose to the iacv.

you should really spend 30 minutes taking out the iacv, spraying it with brakleen, using a toothbrush or something to scrub off the carbon build-up and then allow sufficient time for it to completely dry before reinstalling it. it may also be the MAF
