Default Car wont start

So i went to move my car tonight and she started bu then began running rougher and rougher and finally died. It happened a couple times before but usually a few more tries and it starts right up. It kinda acts like its flooding. I havent changed the infamous opti yet. Could that be it. She usually runs almost perfect but every once in a while this happens.

did you get a ses light? whens the last time it had new plugs and fuel filter? check fuel pressure, test evap sytem, and yes it could be the opti.

I just bought it a week ago so it I dont know, but honestly I think the plugs have never been changed. It still hasnt given me a check engine light. I scanned it with an OBD2 but the scanner kept saying "scan failed".

yah 95 is a obd2 plugin and obd1 computer. you will need a scanner that will work on your yr. or you can make a obd1 scanner work with jumper wires. http://shbox.com/1/xraycable.jpg

It almost seems like my car only does this when it sits and gets hot. Took it out today and it ran fine, I dont think it missed at all.
