You might need to reset the adaptation values, noting the age of the car.
If the fuel trim and maf was way out, losing battery power can cause this. The car needs to re-learn it's parameters.

I am looking into this now. sounds like it might be it.. Do I need have a dealer do this or is this something I can do myself? what I'm finding so far requires a tool from snap on or the likes.. any more info would be a huge help.. thanks in advance!

It's probably best to let someone who knows, use a scanner and relearn the car. The scanner costs a fortune, and it takes a bit of know how to do it right. IMHO.

Does this car have OVP relay? Or is that only on older ones?

Well at lunch my buddy came over and we hooked it up to find the fault codes. Before we hooked it up to the computer we unpluged the MAF sensor thinking that it might run on a default code. this didn't seem to be the case cause then it wouldn't idle at all before stalling out. We plugged it back in and when we first hooked up the computer there where no codes. This makes sense casue I just cleared out the ECU by disconnecting the battery for a while. We started it up and let it run as long as it could and it came up with the code P0302 cylinder 2 misfire. that was the only code. It seems to be running super rich as all we could smell is gas while it was running.

Any thoughts?

The fuel trim needs to be reset, and the misfire probably comes from the rich mixture.

The scanner needs to be a MB tool, or a Snap On model with the correct software.
