Re: 1993 k1500 4.3L spits & spudders during drive
it has been gradually getting worse now that it has been a few weeks with out no fix, i've done everything i could think of on my own. now i noticed that at a idle the motor loops, like revs up slightly and drops over and over, maybe the fuel pressure regulator??? but i changed it about almost 2 years ago with a knock off brand could it go bad agian ???? any idea's thanks
