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.

this is a Camry 5sfe, pretty much the same thing. He shows both taking it apart and Not taking it apart.

I did this cleaning with carb cleaner, however, Box had said in the other thread that there may be a gasket needed to be replaced in the IACV. Is it the gasket that is below the throttle body the one that would need replacing? Also I replaced all the hosing today since I went to autozone anyways, and there was one hose that was cracked, which then shattered when I pulled it out.

Just trying to get a handle on what else could be the cause of my car's problem of starting.
