Question about 1998 Plymouth Breeze
Took car to Auto Zone for diagnostic check. Below is a copy of what I was given.
Definition: Catalyst efficiency low - bank 1
The oxygen sensors monitor the catalytic converters ability to store oxygen.
1. - Catalytic converter defective (Failure possibly due to #2, 3, or 4.)
2. - Engine misfire or running condition
3. - Large vacuum leak
4. - Engine oil leakage into exhaust - valve guide seals, piston rings.
I would greatly appreciate it if you could tell me what to check, or what the problem may be.
Regarding the o2 sensor code check any injector block or malfuntion as well

Your O2 sensor up stream is gone and the engine is sucking air probably your pcv valve hose and is sucking oil straight into head and out D tail pipe! you have some good looking over to do on this by the sounds of it but do you notice oil missing a lot or do you bother to check and I would do a compression check on it before I spend any more cash on it!!! so start with compression test! see specks on line for suggested test pounds 145 pound per cylinder???net
