That sounds like a**.. no offense. It almost sounds like ticking lifters, what kind of oil are you running?

Ohm out the injector. If it's not around 12.6 then it's bad and will lean out that cylinder

Well so it turned out i had a vacuum leak, connectors to injectors were butt connected. I was leaking/squirting out fuel through some lines, wrong battery and wrong hoses. now i need a Transistor harness if anyone has one or can get one message me.
