Sorry, had to eat dinner, P1351 is for ignition control module high voltage, Tell me everything that you have replaced, Give me a little more detail on the misfire, does it do it at idle, or just once in awhile, or all of the time, when did this start.

Just once in awhile and only a certain rpms like 1 grand and 2 grand then it quits. Distrubotor. Crank senor. Pick up coil. Ingnation model. Fuel pump and filter.# 5 injector. Starter. Spark plugs and wires. Map senors. Mass air flow senor oxygen senor. Think thats everything and when its cold it starts right up then after warming up first start shuts down and then starts right bk up. When we put the distrubtor in the garage said it was in time they helped us do it with a computer.

Ok, so when it quits that p1351 code appears? What about the coil, was that replaced, when you say pick up coil are you talking about the cam sensor which is in the distributor? This sounds like it could be a connection issue, Look closely at the wiring from the Ignition control module to the ignition coil, do a tug test(pull, tug on wires) while its running, looking for any change in runnability, I have seen the wires in that area break or have poor terminal contact.

My coil is not in my distributor its my ignation coil the only one we have.

Also its missfiring bad and using gas really bad like it nevers has before.

Do u think are engine control computer can be bad someone else told us that and I was wondering if that could be it?
