It could be 02 sensor running the car lean - they're a 30k miles
service item.

Make sure your exhaust is hot when you test... running an hour on the
highway right before testing might help the cat. You might also want
to make sure your cat is OK, not plugged, etc

Could also be a vacuum leak causing a lean condition.
