Okay, for the life of me I have totally forgotten what controls the Idle increase when you turn the A/C on. This car has cold A/C, but if it's idling and you turn the A/C on, it will sputter out and die (or try to real hard). I think it's a switch somewhere, but I just can't remember which one it is, or where it is for that matter, lol.

Also, it's running great... until you've driven it for an hour or so, then it starts trying to die when you pull up to a stop sign/red light. If you let it cool down, it starts working great again. Any Suggestions?

I have:

Replaced Coil pack, TPS, IAC, PCV, Plugs, Wires. Next on my hit list is Fuel Pump + filter. Not sure what else it could be causing this (except MAYBE Vacuum line somewhere...)
