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

 

Where did you you get the replacement throttle body?
