OPTI SPARK CODE 42 OPEN LOOP ONLY
DRIVING HOME FROM WORK JUST ABOUT HOME AND THE CK ENG LIGHT STARTED COMING ON AND IGN MISFIRING. GOT MY WIFE TO PICK ME UP AND CALLED A FRIEND OF MINE AND HE SUGGESTED A MODULE, GOT ONE FROM CHEVROLET AND INSTALLED ON CAR RAN FINE FOR ABOUT 1/2 HOUR AND STARTED RUNNING THE SAME WAY. HOOKED UP READER AND CODE 42 ACTIVE. TALKED TO MECHANIC AT THE CHEVY DEALER HE SUGGESTED REPLACING THE DISTRIBUTOR SEEING HOW THE COIL HAD ALLREADY BEEN REPLACED EARLIER. SO AFTER REPLACING DISTRIBUTOR THE CODE COMES UP WHEN ENGINE IS IN OPEN LOOP AS SOON AS IT GOES TO CLOSED LOOP CK ENG LIGHT GOES OUT AND NO OTHER PROBLEMS SHOW UP UNTIL ECU GOES BACK TO OPEN LOOP. ANY SUGGESTIONS. :smash:
