Running very rough. Check engine light comes on, but does not stay.
Checked codes and got P0300 and P0308 (misfires) and O2 sensor B2S1 slow response.
Change all spark plugs and coil packs and both O2 sensors on right side of engine.
I am lost. Is it the ECU? One shop told me it could be head gasket leak. But they were not sure.
have the same problem?
