last night i raced a mustang GT i run a dry 60 shot. sprayed fine.. car performed well, but threw a check engine light (AFTER THE RACE).. i unfortunately was not in a position to check the code... so i checked the plugs.. NO damage.. reset the ecu.. let it cool down. started it up.. NO cel.. the only thing i can think of is i bumped DOWN my fuel pressure a couple days ago because i was running rich, and knew i could realize some more power without leaning out.. MAYBE it was a little too lean?? and it threw a code JUST on juice, cause i drove home.. NO CEL.. got on it a little.. NO CEL engaged vtec.. NO cel.. so i think maybe it is a leaning on juice issue.. im about to go run it on spray shortly to see if it will throw the code again.. i know without knowing what code it was it is hard for anyone to say, but does anyone have ANY ideas???
