Twiglet240 is an unknown quantity at this point
Took my car for a ride with the o2 sensor unplugged and it ran pretty much the same. I got a new one coming but I don't think this is the issue. I'm starting to think its my mafs.

I don't think its my fuel pump because when its cold it runs good and makes power. The pump would have to be crapping out when it gets warm, but it seems to me that the car is running pig rich, not lean.
