QuestionHello, I need a repair hero! Heres the problem. My truck runs great when its cold, great acceleration, overall happy. Hers where it gets tricky. Two problems, When the truck is warm, and I start to climb a hill ONLY ON THE FREEWAY, it shutters real hard skips etc. When I get top the top and plane out all is well. It does not do it at low speeds. I have replaced to date main fuel pump, fuel pump relay, fuel filter,idle control on throttle body. And have had my injectors cleaned. $2000 in shop bills so far, still not fixed. Second problem, When the truck gets hot on hot days, the truck coughs , misses, pops, and then eventually dies ANYWHERE! When cooled enough its fires and runs home. I understand they have many sensors, could that be? Please help if you can. Thanks
AnswerTo start with,have you're catalytic converter checked to make sure it's not clogging up.This is an easy check at most garages,they just need an infrared thermometer.With that kind of money,check to see if you're $2000 already checked that.Second of all,how did the fuel pressure test out,has it been tested?When you describe you're first problem as a shutter,do you mean a transmission shutter?Have that looked at also.
