Reduced engine power and engine light. have had just about everything replaced i have my repair bills. truck will run fine after being in shop then starts all over again. throttle body has been replaced twice. it will drop me down to 20mph on the highway and i am afraid it is going to cause a bad wreck. it happened to me today and i am out of town i have drove 600 miles with a horse trailer to pick up a rescue horse and am afraid to start home with no clue what is wrong with this truck when i reset the battery it will work fine but i am telling you that it is going to cause a bad wreck. i don't mind paying for it just tell what the hell is wrong so i can get it fixed probably before someone gets hurt or killed.
