Engine light came on. Stopped and had it checked. Showed P0430, Catalyst below threshold. Any suggestions? 99 CVPI 4.6L 116000 miles? Need anything else, let me know. Thanks in advance.

Try cleaning the Mass AIr Flow sensor with carb cleaner or brake cleaner. Do you happen to have a K&N air filter? Also cheack for any exhaust leaks.

If none of that works hook up a scan tool and see what the O2 sensors are doing on bank 2. Compare up stream and down stream switch rate. The downstream O2 sensor should switch alot slower then the upstream O2 sensor. If the up stream and down stream switch rate is about the same replace the bank 2 (passenger side) catalytic converter.
