last week the truck was runngin great and i went to change lanes on the highway and it started to feel like it had a miss (dead cylinder). so i get home and leave it for the next day. i start it put its not missing when its cold it warms up and starts to do it.i put my MSD on its ok for about 5 blocks then starts missing but not as bad. i change injectors, it takes longer for it to happen then does it badly. change plugs today and it was good for about 30 minutes and it started all over again and now its really bad.

ive changed injectors, plugs (FR3LS6 ac delco i have broidix heads) distributor cap rotor
the only thing used are my wires and coil. the wires are in good shape but i might change them just to eliminate them from the picture of bad things. i put the MSD in to help narrow down my issue

any thought before i go NUTS. my next step is to pull the motor. i want to get rid of these heads and do a regular setup like everyone else!!! please anyone let me know nwhat you think...

for a quick check to see if it's the wires, just grab a set at autozone. one of them lifetime warranty ones. if you still have the problem, take 'em back.

If its not the plugs wires or cap rotor, then look into the ign module.

I had intermittent ign problems that were solved by going through the distributor and a new coil.
