Some Camaros with the port fuel engine may experience complaints of check engine light and poor driveability. It has been
determined that Mass Air Flow Sensors have been replaced and in many cases have not corrected the complaint.
If this condition occurs and a Code 34 is found stored in the ECM, the following steps should be taken.
1.
Check engine for vacuum leaks.
2.
Set minimum idle speed to 500 RPM as described in your 1985 Shop Manual. (Chevrolet page 6E3-145)
3.
Perform diagnostic check for Code 34 found in your 1985 Shop Manual. (Chevrolet page 6E3-101)
