No power and ruff idle

After resetting my apps by pulling the negative off the batteries for a hr.

After about a minute it starts lopeing.

I loosened each injector. When I came to injector 3 it didnt change the idle. So I swapped it out with the 4 th injector.

It stayed on number three not changing the idle. Number for did when I broke the line loose.

There is fuel coming out of 3.

I also swapped out the injector tubes.

It still stays on number 4.

Any ideas

Is it a lope or a miss?

I guess a miss. It pings to. Sounds sorta like a power stroke.

If you verified fuel comes out of #3 and you swapped a known good injector over to #3 and nothing changed then I would check compression should be around 240 psi and 255 psi for H.O.

Have you got excessive blowby coming out your crankcase breather or oil fill?

THis issue remains on the #3 cylinder correct?
You put injector #4 in to cylinder #3 and you got no change.
and you put injector #3 into cylnder four and it changed when you cracked the line correct?

Sorry got a little confused with what you meant by it stayed with #4
