What is your question?
06 grand prix w/3800 has a constant misfire. Obd2 code reader tells me its a random misfire in multiple cylinders but its always the same constant misfire. Replaced plugs, wIres,all 3 coils, & cleaned the throttle body. Ran great previously with no issues & 1 morning it had the miss & still does. Any advice on the direction i should go next will be greatly appreciated..
What makes this problem better or worse?
