I went out to warm my car up yesterday. I started it and it started just fine and went back inside. When I went to leave 10/15 min later my car was running very rough and the check engine light was flashing. I tryed revving it up a little bit for a minute or so and didn't change. Now it barely ideals and runs super rough with the check engine light flashing. I didn't drive it then and left it parked. Today I tryed starting it again and it didn't want to start. I had to give it a little gas to get it started and still ran super rough with the light still flashing. I'm wondering if anyone might know what's causing this? Thanks for any help.

most likely ignition which leads to bad cat which leads to blown engine.

Could be flooded too.

I don't believe it's flooded. It does still start and run just doesn't hardly ideal and runs super rough. I'm picking up some new coils and plugs today. I replaced the plus and wires not to long ago but have never replaced the coils so they have 100000+ miles on them.

Surprised they lasted that long. BE sure to check your catalytic converter for clogging, if they completely failed now, the coils may have been running weak for a very long time before, which leads to catalytic failure, which leads to engine failure.
