P0302 KIA - not the plugs...

Question

We repleaced the plugs, and we are going to swap around the coils to test them tomorrow, i just wanted to know if there is a more common issue here, between the plugs, coils, or injectors. Thanks for any sugestions.... shelly.

Answer 1

Well swapping the coils should be the next step, if you guys already checked for intake air leak. If after swapping coils, cylinder 2 is miss firing do a compression test. If everything looks good you can measure the resistance of the injector.
