General Troubleshooting and Technical Help
I have a 2009 2.5x auto forester with 170k miles.
A week ago I got a p0028 code for the bank on the left side. Fixed the oil level then the code went away. But now reaptedly I am getting a P0303 code for cylinder 3 misfiring. So far I have changed the coil pack, spark plug, and spark plug wires...
