Rpms fluctuating at idle.
I have my rpms dropping on my 05 jimmy at idle. The idle stays sometimes at 500-1000, but they drop to almost 200 or stall at times as well. I have checked the vacuum lines and have no cracks. I believe it is the IAC valve or TPS sensor. Could anyone back me on this or should I bust out the emergency cash?
