I can't imagine those symptoms without a pending code at the very least!

Are you _sure_ there are no pending codes?
- Cheapest CAN OBDII scanner on the net that reads DTCs, pending codes, & clears codes

However, if it's the cats, this might help (let us know in those threads if it works):
- How to remove & replace a catalytic converter (1) & how to fix rattling cat shields (1) & BMW P0420 codes related to cats (1) (2) (3) & cat autopsy photos (1) & what kills cats (1) & an EPA fact sheet on catalytic converter warranties (1)
Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
