    is the truck overheating at all? u could find a shop whose scantool has a misfire monitor that will show which cylinder is missing or the shadetree mechanic way, with the truck off un hook all 8 or 6 plug wires, then gentle set them in the plug hole just enough that they barley touch the plug. then crank truck pull each one off one at a time, the plug where truck doesn't change thats the cylinder that is skipping, thats the bad coil.

Buy a spark plug test light at the auto parts store costs 5 to 10 bucks put the plug tester on eash wire then startthe car up and watch the light if it hasa constan arc then it's fine move to the next plug wire and do this proceedure till you find one with an intermant spark if you find one follow that wire to that coil pack and that would be the coil to replace. Note A bad valve or sticking valve can casue this to also a bad fuel injector or rings and last but not least an intake leak on the cylinder. Please rate if this was helpful.

Have you checked all fuel injectors? Miss fire data is determined by ignition miss. I would also double check that all plug wires are fully seated on plug

Missing have had new plugs in distributer and rotor plugs wires replaced an it still misses and what is a ECM and where can it be found

Before you go all out and buy an ECM I would check with your ignition coil. The middle wire that goes from your distirbuter cap will lead you right to the ignition coil. It could be sparking on something metal around that area. Hope this helps, James Booth

You may get one bad spark plug in 50 years of driving

Does that answer your question?

You did not diagnose your problem, which
was a misfire.

Do you have codes PO301 thru PO306?

Getting a intermittant misfire and an occasional srvc eng soon light sthe code says misfire cyl 1 but after i reset the light i goes back to intermittant missing

Check your ignition coils. If you don't have a coil for each plug then I'd bet thats going to be your problem. That or your spark plugs. I'd start with the coil that cylinder 1 runs through first though.

I think that the coil packs has installed wrong because you said that the problem started when you replaced them... so i think you should re-install.
