Question about 1992 Chevrolet Suburban
Hi i have a 1992 suburban and i had the emission testing done and it failed. they said all the tests passed except for the curb idle. can you please tell me what it could be and what i can do to make it pass the test?
Could be the ECM that controls the fuel supply and mixture to the throttle body .
