Find out why the engine light is coming on, it is the info u probably need to fix the running rough problem. Most auto parts stores will read the codes stored in your trucks computer for free, write them down, and ask what they mean and how to correct the problem. If u need more info, return to this site w/ codes for further help.

actually i would say no because there are 6 cyl transmissions with 4 frction plates and v8's have 5 friction plates in the forward planetary gear

You engine is TBI, It uses a MAP sensor check the vacuum line for crack and make sure yo have a good seal, The distributor also check and make sure the pick up does not have corrosion which causes the relutor to stick. As for the EGR it would cause a misfire, and yes the do fail. I am sticking with the IAC as a problem its a stepper motor and has a high failure rate, chack also the ECT (engine coolant temp sensor) for corrosion that gives false reading.

1 of two things I can think of, throttle body is dirty or intake manifold gasket needs to be replaced. I had both replaced at separate times. Throttle body was cleaned and my tpms went back to normal. Then just at the beginning of this year, Ron were low and misfiring random. Intake manifold gasket solved that.
