2004 Kia Optima 4 cyl Two Wheel Drive Manual 60000 miles
I keep getting a P0303 code. I have changed plugs, wires, coils, and injectors, and the code keeps coming back. The code always comes up twice if this means anything. The spark plug looks fine. I will check compression this weekend. Assuming that this is good, what next? The car runs and drives good. Help!
