I have done everything and still misfire help!
I have a 95 z28 motor n my 94 ta, I bought it and it had a misfire n 2 cylinders so I changed plugs wires cap and rotor and still misfire then I did new head gaskets and laped the valves cleaned and replaced all bad wire connectors on the engine wire harness and still missfire! There is no check engine light on and the spark plugs are clean when I pull them after running the motor. I'm realy loosing my mind chasing this problem. It's a misfire in 2 cylinders. Can someone pls give me some advise on wat to do!

Thank u all for ur advise, I double checked the fireing order and the wires are correct and I took the time to run them the stock way. I did check the power to the injectors with an ohm meter too, it is 4 and 6 that r misfiring. I inspected the crap outa the wiring harnass and I'm pretty possitive I replaced all the cracked wires and bad wire clips, I haven't replaced the coil tho can that cause just 2 cylinders to misfire? I checked for spark and I am getting spark n both those cylinders too, is it posible that they r sparking at the wrong time? Again thank u for ur advise.
