HIGH, ROUGH, OR UNSTABLE IDLE ON 5.0L ENGINES - 1982-83 FIREBIRD
High, rough, or unstable idle condition may be caused by vacuum leaks by the TBI cover plate to inlet gasket area on Firebird crossfire injection engines.
When this occurs, check the entire area of the TBI cover plate gasket for vacuum leaks.
If leaks are detected, remove the cover plate and gasket, replace the gasket (Part Number 14044605), reinstall the cover plate, finger start the attaching
bolts and studs and tighten to 20-34 N-m (15-25 ft.lbs.).
