I have 3 codes total. P0420: Bank 1 Cat Efficiency Low, P0307: Multiple Cylinder Misfire and P1285: Cylinder Head Over Temp.
I hade a coil go out.. no supprise, and didnt fix it right away. I then had a second coil go out so I had them both replaced as well as the plugs. They were cylinders #5 & #7. Replacing these did not solve the misfire. Upon further inspection taking the coils back off i have found that the plugs are not firing at all. What could be causing this? Could it be a timing sensor? how do i test for that?
