5.0 motor is fully build my question is the at times when im driving my car it cuts out and then responds and cuts out again kind off like if my tps is bad but i checked it and even put a new one in and i still have the problem????


I also got a dignostic check and they couldnt figure out the problem im hoping some one on this forum will. Thanks in advance
