How would I check the coil? I don't think thats the problem since the coil and wires are both fairly new. Also, how would I find evidence of a bad IAC? Right now the IAC is the only thing keeping the idle even remotely stable so I don't want to replace it if its still good. Also, I'm tired of replacing items because they "might" be the problem. This theory is getting expensive.
