Erratic Idle
My 7M idles terribly. When its cold it raises idle properly, but once warm jumps from 1000-2000 rpm's or so back and forth. I have checked the Throttle Position Sensor, the Idle Speed Control Valve and the Cold Start Injector in the way the FSM says and they all check out good... I'm lost and need to fix this, as the truck is close to ready to drive.
P.S. it is not pulling a check engine light, or any codes. Thanks for any help!
