I get to codes my check engine light flashing codes that come up is P0300
and P1654. I know that p0300 is a radom misfire I checked and changed all my spark plugs which were pretty worn out and checked spark plug wires and spark. the car was running rough idle and since i changed the plugs it made it run a lot better and now i can't clear this code. could the tempture sensor have anything do about this or the oxygen sensor.

you asked what code p1654 was and that was it. the service engine light doesn't only go on because of engine problems.
