318 mystery problem, somewhat solved!

I've got a handheld that gives me everything bit of info on the sensors which is great.

If I disconnect the IAC motor it'll give me an error and won't work I do believe, I may be able to pull the motor out of the throttle body, leaving it hooked up I think that should work. I'll try that.

Acceleration: There is a setting, call "acceleration fuel" on it that I can adjust. It's at "00" right now which is the base setting, I can set it negative for less and positive for more when you hit the throttle. I'll leave it there for now.

Cruise: That's much leaner than what I have been running it so that could be it, (hopefully haha) How much advance would you say it should be generally speaking? I've got around 16* initial at idle at around 35* all in at 2500 rpm with 10* of vac adv. The vac. adv. is on a slower curve then some others so I can speed that up.

I am worried about the overheating issue though, leaning it out more is going to raise the temp of the engine right?
