If one cleaning seemed to work but the problem returned fairly quickly
you might want to have a looked at the crankcase ventilation system.
See if you are getting a significant amount of oil blown into the air
filter - if so, then the fumes from that will re-coat the throttle
body pretty quickly.

You asked later about pulling the IAC - unplug the connector, two
screws, and slide it out. DO NOT TURN THE IGNITION ON WHILE IT'S OUT
- it will spray parts across the garage (I know, and it a b!@#$ to get
back together!). Then clean the shaft and the pintle (the end of the
thing) with cleaner. Before you put it back, clean the port it sits
in from the outside as well as from the top of the throttle body.
That hole doesn't seem to clean very well with everything in place.
You should need no adjustment - just put it back. I usually use a
very thin coating of (sensor safe) RTV on the gasket to prevent leaks.

Take doodad # 2 off the throttle body, you'll find black carbon
soot to clean of the worm and slide valve.

Yes, I deleted, my post once I saw the they had added a miniature
gravity tester. That wasn't there during my hay day, as the Delco
batteries died we just used the water level indicator in other batteries
for looks.
