My passat has 103K and I've just changed the spark plugs from bosch F7LTCR to NGK BKR6Q and drove around for maybe an hour. My check engine light came on so I drove to Autozone and two codes came up, P1136 and p1250. I don't know if it's spark plug related but does anyone know what could be the problem?
My engine is not moded. Thanks.
