    1999 Idle Probs

    My Tahoe is idling rough...Hooked it to the comp..threw 22 troubles. All 4 O2 sensors and mass air flow sensor. Would replacing the mass air flow eliminate most of these troubles?

    1999 Idle Probs

    Ive got a 1999 Tahoe Lt 4x4...When its in park it "shudders" so to speak. Hooked it to the comp and it showed 22 codes... All were O2 sensor codes from all 4 sensors. It also showed a Mass Air flow sensor code as well. Would replacing the Mass air flow sensor get rid of most the O2 codes?
