HIGH IDLE PROBLEM ON GOING

1996 Ford Thunderbird

Engine Performance problem
1996 Ford Thunderbird 6 cyl Two Wheel Drive Automatic 210000 miles

#1: Dose the cannister purge valve stay open or closed while engine is running.
#2: Purge valve is operating correctly when I done a bench test on.
#3: If it is supposed to stay open while running, if it does not stay open will that cause the the high idle problem.

If it is closed, it shouldn't cause a high idle. Have you checked for vacuum leaks? Also, has the throttle position sensor been checked?
