I have a 99 ls1 in my 54 chevy truck the wiring harness has been re worked to remove all the wire not needed for street rod also computer has been reprogramed. My problem is no 3 and no 5 have a dead miss. Have compression fire from the coils. The injectors are clicking so have a signal from the computer Have changed coils plugs wires injector and still a dead miss on the two cylinder. Any body run into this prob before Thanks Ron
