Maybe, start with what engine, etc, etc, and what you've done to it??
Have you checked the following?
plugs
wires
Coils/module
valve train
injectors, and associated wiring
done a leakdown?
done a comp test?
what are you using for diagnostics?
Folks can't do much without some basic info....

sorry new je pistons,50#inj. leak down was 8%,comp check 135 alway around have not changed the coil pack or module changed the #1 injector and swap it with #5 still had a little miss think i need to change the coil & module

I would start with coils and module . I think the grounds are not right on the car you are talking about. The wiring is in bad shape it needs A new wiring harness it has been cut up bad . It A good chance the ECM is bad with all the wiring and grounds like they are.

You would have a miss on 2 cylinders if the coil or module was the culprit. Id check the plug/wire first.
