When the car first starts, its Idling a bit high. Then it slows to almost stalling, but when I turn on the AC it goes back up to an insanely high speed. I got a SES light, but haven't decoded it yet. I'll do that now.

Yesterday, I cleaned off the ECU contacts wich were horribly corroded. Maybe I didn't dry them well enough? I'll post back later with more info.
 
Did this start right after you cleaned them? If not, maybe a bad MAF sensor. Do you have a scan tool? Any #'s?
 
No scan tool, I'll order the latest turbolink as soon as my daily driver is out of the shop. I got a code for the ESC so I cleaned the coil pack's harness and it went away. I ended up adjusting the TPS sensor and the problems went away. I'll check it today with a voltmeter to see if I'm in the zone.
