I have a post on 911, but haven't had much help. Can some one tell me where to go from here? My truck just falls on its face after 2000 rpm. It cuts out, stumbles, and smokes some too. After 60mph, I can have it floored and it takes a good five miles to get it past 70 mph. The only obd code I can get out of it is a po 382 intake heater. I don't think it is related. the lift pump is brand new, the fuel filter is about two weeks old. I am just at a loss. Does anyone have an Idea, Injectors maybe? anything???:{
