Help with miss/stumble/pop


New Member
Having a weird issue and looking for some help. I have an engine miss you can feel and hear from the exhaust. I tested the following in closed loop at approx 1400 rpm.
I have just tested and retested by pulling each injector one by one to see if I can isolate the cylinder. Each injector for each cylinder I pulled I noticed a drop in rpm and a difference. engine miss disappeared once I pulled an injector on every one. I heard no pop from exhaust and heard no stumble. Hard to believe I know but this is my issue. Car has translator,TT chip,new ignition system,new fuel pump,60 lb injectors. Numbers are-
Iac- 17
O2- low 800's
