iacv valve
i been having an idling problem and the ecu code i pulled out was the IAC. I took the Iac out and cleaned it. I sprayed the whole thing with carbon cleaner. It would drive regular for a couple of hours. then the rvs would gradually go up and not idle as well. Then acouple of days later the idling gets worse until i spray some more carbon cleaner. HAs anyone had this experience. Could a high purge of fuel vapor in the evaporative emission canister or valve effect this?

If you are having problems with idling when the engine is warm, it could also be the Fast Idle Thermo Valve. It is located below the air intake connection and is held on with three bolts. Also make sure that your coolant level is good and bleed any air out of the coolant lines using the bleed valve. These idle control valves need a good flow of coolant to work properly because they depend on the coolant temp.

Find where the upper radiator attaches to the engine. About 2-3 inches to the right of that there should be a small bleed nipple that you can use to bleed out the air. I believe it is a 12 mm bolt. Make sure your radiator is full, put a shop towel under the valve, then loosen it until coolant starts to flow out with no bubbles.

OK, I'll try a pic:
You bleed it on a cool engine (not running) after filling the radiator with 50/50. Then remove the cap and fill it up again. Then run the engine until the fan kicks on, shut it off and check the level again. Thats about it.
