I put new coils in last week (JJR) and yesterday car (series 1 R33) started running like a dog as soon as the car starts making boost it misfires to the point it almost stalls, back off and it runs perfect again, it idles perfect as well, was thinking maybe my ignition module was stuffed any ideas? it was running the series 2 ecu as well (not sure if that matters)
I chucked in my PFC and problem was still there.
