I just put a brand new electric throttle body on my truck along with a new fuel throttle control module and a new mass air flow sensor Truck was driving perfectly for about a week. All of a sudden it started idling high in park. It takes a few moments then it’ll idle correctly. But when i try to drive it the engine light come on and i get a message reduced engine power. I reset it with my scanner once i do that it idles high again, soon as i put it in drive and press the gas, engine light comes on again and i get the same message reduced engine power. I tried to do a throttle position re learn by letting it run for 3 minutes and then cutting it off for 60 seconds. I took the throttle body off it still looked new, but i cleaned it anyway. Unhooked my battery for about 20 minutes. Still no dice, having same problems. Does anyone know what needs to be done? Thanks
