unburned fuel makes me think that its either a bad O2 or possibly even a fried valve. if it's running rich as hell then it must be the O2 sensors. id check that if i were you.

run it dry, put in a gallon and run it dry and see how many miles you get. Could be a bad guage.

I figured it out. Alternator was taking a ****. I replaced it and the car feels 100x better. My battery was getting drained out from running the car without charging right and probably not getting strong enough spark.

I had an alternator go out before. In my case it just died quickly so it was easier to determine that as the problem.

Yea man, those electrical Gremlins will get you everytime. That is weird that you didn't notice your lights or gauges acting up though. Im glad you got it fixed !!

typically you notice either your volt gauge is really fluctuating with your blinkers or system on (how i noticed it on my old truck) or your headlights look really dim. i agree though they usually go out pretty quickly when it happens to be that time.
