I have a 91 V8Q w/ a 5 spd. The engine idle is inconsistent - it seems to 'hunt' for proper idle speed and will stall on occaision. It used to shut down while running at speed. This has not occured in a while. I did have two breather hoses replaced recently which made a difference. Spark plugs, wires and rotor caps are near new. Idle Stabilizer Valve is also new. Any thoughts?
