Actually, after I re-fueled, the problem corrected itself. What had me baffled was that it didn't start acting up until the bottom half of the tank. If it was bad gas, you'd think it would have acted up almost immediately after fueling.
When I try to start the car after it sits overnight, the engine floods itself to the point that it just can't quite take off. When I shut off the fuel flow into the engine (pull out injector fuse), it starts then stalls (obviously), put the fuse back in, starts and runs rough for about 1 second, then runs great and starts everytime the rest of the day.
After my car sits overnight, when trying to start it for the first time, it floods itself while cranking to the point that it won't quite take off. I knew if I shut off the fuel to the cylinders, it would probably clean itself out and start. I found the injector fuse, pulled it out. Cranked the engine over, it started, ran for a second, and died. Put fuse back in, cranked engine over, it started, ran rough for a second, then ran normally. For the rest of the day, it starts and runs normally. Any ideas?
