Major friggin headache

Ok, some of you had it right. It was the Cat!!! I happened to be underneath looking at something else and bumped the cat and heard something rolling around in there. We cut the cat off and drove it and has great power now! Getting the new cat put up tomorrow. Thanks for the replies everyone!

There you go with that "almost" again!
hauntedwinter, it's very possible that pouring raw gas into the cat converter from your cylinder misfire is what overheated and trashed the cat. You did have a #3 cylinder misfire error, and I'm willing to bet that's what trashed the cat. Don't dismiss the misfire code.

There is a very good chance the "hit" that took place on the cat did not cause all of your probems. There is a good chance that the pluged cat was cause by the miss fire. If this car was in my bay I would recommend Pugs, wires, load test the coils , replace as needed. Replace the 2 forward O2 sensors after your sure the miss is fixed. Any time a car has a miss or a plugged cat is very hard on the O2 sensor.
