Toyota idle problem carb model

1988 Toyota Tercel with 116k miles sat for 4 years. Runs great at driving speed, but the idle is good when cold, but rough (low) when warm, or will idle ok when warm, but drops low when a/c turned on. The idle increases when the a/c is turned on like it is suppose to but is rough (lobes). I have flushed carb, changed vaccum hoses that were cracked, replaced fuel filter, etc. All the basics. This car is a California model with lots of vaccum and emissions stuff. Any idea of which vaccum valve, module sensor, or other items might be causing the idle problems? There a thermal air valve in the air cleaner, egr modulator, a bunch of other stuff. HELP thanks
