After all my searching and rubbing the back of my head, I think I finally found my prob. It was idling up and down, and would shut off. Its still alittle rich, but at least it idles...lol. I found that the sensor on the passenger side on top toward the front of the throttle body was unplugged. What id that sensor??

shouldnt do anything, will keep the system in open loop. same thing with the map. open loop = rich condition. you should have gotten codes for those. have it scanned and write em down and have it cleared. take one of the 02 sensors out and see if there fouled ( all black ) if so you could try cleaning them with a propane torch, heating up the sensor end till the black stuff burns off. dont get so hot at to melt the wires at the other end. if its run rich for a time the 02's and spark plugs will suffer and if fouled should be replaced.

I have tried several times with the software I got with the car to connect, but I have had no luck. I would like to get these code, guess I may have to drive to advance auto parts...lol
when my map was unplugged it barely ran, popped and shook, skipped until I floored it. plugged it back up and ran lots better.
