Cleaning the IAC (Idle Air Control) Valve--how to? Options

[mnwolftrack]

My '94 GT was having trouble holding idle this morning right after a cold startup. It would die unless I held the gas and kept the RPMs around 2000. If I let off the gas, the RPM's would drop to around 200 and then it would sputter out and die. After about a minute, the problem went away.

According to some research on this board, it's the idle air control valve. I read some references to people stating they were going to clean it or did clean it, but I didn't see any information on how to actually clean it.

P.S. I just put new plugs in, and a cap and rotor. The problem above only happened this morning and about a week after I gave it the tune up. I have only owned this car a month, but I have noticed the idle seems to drift a little--sometimes it's idling around 500 and shakes the car a little when fully warmed up, and sometimes it idles just fine around 800 when fully warmed up.

Before I actually replace the IAC, I want to try cleaning it but want to see what others have done. Once I clean it, then I will re-check the timing.
