Allright, I cant seem to diagnose my problem. My car starts up great and runs like it should but if you drive it for a bit and it warms up then it starts running suuuuuuuper rich. It wont idel and I get black smoke and studdering when I do get it to stay running.

Im guessing its some sort of sensor but I cant seem to pinpoint what the hell would be causing it.

THANKS in advance.

Try cleaning your MAF, and check for fouled plugs.
