96' vortec, she has a lil miss at idle, #5 and 7 miss #5 is worse. I can rev up or power stall and it seems to go away, scanned and got a p0300 and o2 code for that bank. replaced plugs, wires, cap, and rotor. Miss is still there! checked and my short fuel trims are trying to take away like -14%. At this point im thinking either injectors or valve. Going to run manual compression test in a couple days just to rule a copression issue out. any ideas? sugestions?
