Troubleshooting my car! help make it run!

well, its not fresh. I mean it sat over winter, but ive filled up since then. I would think it would run this consistantly bad if it were fuel.... new filter too. I did just change out the ECU with a new cheapy one. It didnt seem to have an affect. The old one was melted a little though, I could see the 2 little red tube thingys.
