That is the tester I have been using when testing the spark, compression is at 140, I have looked and listened for any vacuum leaks, and I don't understand how an injector could cause a loss of spark.

I'm saying i don't believe you do have a loss of spark. You would have found it by now.

Okay when you are watching the tester and you see a spark occurring at idle and as you slowly accel it starts to break up and around 1500 it goes away totally and then comes back weak around 3500/4000rpm. I agree I think I would have located it by now, but I must be over looking something.

Ok....you need to walk away from this one for a couple of days and not think about it.......seriously....
Then get your old, squeeling dist that ran fine and put it back in, triple check your firing order AND rotation (take the cap off, have someone crank the engine and look at which way the rotor is turning) and make sure you've got the firing order going in the right direction..........and see where that takes you.....

Thanks Sidom

Okay am I wrong in thinking that with all that I have changed that the only thing left would be the eec. Is there anyway to test the eec or will it throw any codes.
OKAY I just replaced PCM and it is still missing on 1 post on dist cap it isn't a particular cylinder just whatever one is plugged into that post. I have replaced distributor 3 times with new ICM on each one,cap & rotor, plugs, plug wires, coil and PCM. I have wiggled wires while running sprayed electrical cleaner on connections. I am stumped.
