Engine code keeps returning (check engine light, code p0300 random mis-fire, plus cyl 1-6), erased codes with my reader several times. Engine seems to be running fine. When I took it to Firestone they put sea foam in the tank. charged $68 to read the codes that I already told them what they where, $10 for the sea foam, and $100 for spark plugs.
