Help, codes p0021 p0300
Changed out my valve cover gaskets a few days ago. Everything was running fine then out of the nowhere these codes came up. Car starts up fine but after it warms up it idles rough.
Changed out the cam position sensor bank 2, also did oil change,oil filter, coil change, still need spark plugs(ngk iridum remain)
