idle issue

[hokie7t5]

Have a 240 sundeck with 5.7 Mercruiser. Engine is erratic when it idles. Will die down then surge and sometimes even stall out. Will start back up just fine.
orks great when I "power up" in gear and cruises just fine.

IAC valve should take care of it... fairly common failure.
