No - cylinders 1, 4, 8 were fouled. Each on it's own coil.

It seems like a type of cross-fire or miss-fire signal. But if it was really random and crazy I think I would get hot, violent pops out the intake and exhaust. These are little sneezes at idle.

If the compression stroke miss-fired, 180 degrees later the exhaust is opening, wasted spark fires when the mating cylinder is at TDC. Could the exhaust side partially fire and still have some pop left when the intake opens?

Closing the loop fellows. I finally broke down and went to the junk yard and bought a new coil and EDIS. Turns out one of my coils was BAD! I swapped the EDIS to see if it made any difference - nothing.

Thank you all for your help.

Off to my fuel side and continue my MS II install.
