Missing and bucking when driving 91 4.0L 5 speed
Ok the problem is back...!!!
installed cps,tps,o2 sensors and fuel filter, Cap/rotor plugs/wires. ..ran excellent for a few days but still had a surging idle sometimes. Went down the highway today and yhe missing and bucking started again. ..can someone tell me what may be the problem please ? Could the throttle position sensor or crank position sensor have been ruined or gone bad for driving it while the problem persisted ? Hmmmmm ....I will test these things and hopefully get an answer. Thanks in advance for any help .
