P0302 Chrysler - 300

Question

I started with code P0202 and P0302. I have replaced the ignition coils, the spark plugs and fuel injector on cylinder #2. Now I only have P0302. What else do I need to do?

Answer 1

Hi there,

i would take a compression test on the #2 cylinder. With all that you have done you likely either have a problem inside the engine, a bad head gasket or an intake manifold gasket leak near cylinder 2.
