    an oscilloscope waveform of secondary voltage will show if ignition occurs and progresses to completion (waveform will have specific shapes for good and misfire cases);

    a xenon tube spark tester shows if there was a current pulse (altho this may not be a good indicator);


    ( basically, how do we view inside combustion chamber )
    I used to have a snap on scope but not anymore.

    I have a custom OS and file loaded in the truck. ECU was originally a big block 8.1. Needs this ecu as it has the chip for IAC and not DBW.

    Plugs are (3346) BR7EF.. Started at 28 now down to 21

    I'm not sure which are stronger... use the coils you think are better, and use the dwell table that goes with them.

    You can try increasing dwell say 10-15% and see what happens.

    Hmmm, plug gap is getting narrow.
