could also be a spark issue? Something is just not right with spark and even 2 timing lights are telling you something is not right? So it's set to 0* with bypass disconnected... or 4*
what about bypass connected? Should be around 20* but it is going to be jumping around a little, just part of idle control of the PCM.
What 2 cylinders are glowing? Could there be a crossfire in those 2 spark plug wires? How do the plugs look on those 2 cylinders? Really sounds like a mechanical issue and not something that can be tuned out.
