from what ive read here the 01 cars dont like to not have a working rear o2 sensor, it could be causing over fueling. do a oil change, dont drive with gas filled oil, your engine can die from that.
id check the wires to the o2 for damage then if they look good put a new o2 in there.
check the cylinder 3 plug for damage too. it could just be tune up time for the misfire.
or, the cat could be clogged up. dumping fuel can clog the cat. clogged cat can cause misfires also. and hesitation, and no power.
