Re: need more idle help
There's a lot of missing info that's in your first post, will get better responses with just one thread that has all of the details.
Does your truck pretty much die when you unhook the iac valve? Could be stuck, if it stays the same it is bad. Did the truck have misfires before? Timing is easy enough to check, can't hurt, just pull the SPOUT so the computer isn't advancing the timing. Pulling code might give you some insight, too. Get some vacuum readings if you have a gauge. Still think it's awfully strange that this started happening after a plug change, bet it's something simple,
