Q: Engine misfire, P0300 code
Engine ran fine yesterday, today it has a misfire & flashing CEL. Had the code checked shows p0300. removed spark plugs & they are all clean, light brown. Wouldn't a misfire cause the plugs to be black?The misfire & flashing CEL occurs on acceleration, when coasting the CEL goes out. Had the same problem before & it was the #2 coil, but it had a fouled plug also.
My car has 170000 miles.
My car has an automatic transmission.
