HAS HIGH IDLE & MISFIRE on 1993 Chevrolet Camaro

WHAT IS THE CAUSE?

Asked by for the 1993 Chevrolet Camaro
An engine vacuum leak affecting only one cylinder could cause and engine misfire and high idle condition. I would recommend to find the cause of the engine misfire and get that repaired. Once then engine is running smoothly then recheck the idle and repair as necessary.
