Guys - I went away for 3 months and had to leave my car outdoors in a very shaded area on a battery tender. When I returned to start her up, the engine turns over but won't idle. I have to depress the accelerator a fair amount to keep the engine running.
Previously, last summer, I was having a problem of stalling in extremely hot weather idling at a red light. But never a problem in cold weather.
Any ideas would be appreciated!

One other possible issue - idle control valve sticking.

This ^^^^^^
It's directly related to the period of inactivity. Sticks because it's dried out.
