basically i have searched and came up with the usual(replace cap plugs rotor etc...)
But what i did come accross is that someone had mentioned that cams with agressive lobes sometimes do not hold a "perfect" idle which sometimes throws obd2 ecus off and triggers a misfire code. Has anyone heard of this or should i continue looking. Some people say convert to obd 1 everything will go away?!?!?
basically my problem is misfire on 12&3 that came out of no where.
compression test came back good across the board.
