Question

I have code P0351 on my 2009 Toyota Corolla, how can I fix this?

Answer 1

Hi there

I would try swapping coil #1 with the one next to it and see if the misfire moves. If it does, replace the ignition coil. The coil is actually a more common problem then the spark plugs and the code does point to a coil problem.
