Have an early 03' build, did warren 175/100 sticks, full bulletproof a KC Stage 3 VGT 68mm new HPOP (one failed in a month), LPOP and front cover (gave up my arm for that one). Anyways, the ficm was replaced with an Innovative one spring of 2014. It ran fine since. Did all of the work cab off, and first start it idled fine. After it was warmed up, it idled around 950rpm. If I smash on the brake and hold it to put strain on the engine, and let off slowly, it stays at 650. In gear it idles at 650. This only happens when warm and it's the most annoying thing. I replaced the ficm harness due to some frayed wiring, no luck. It pulls like a train (pulled, my stock tranny went out until further ado), and it ran fine, aside from the higher idle. Anybody ever run in to this??
