Ensure no exhaust leaks up stream of the O2 sensor and that the plug gaps are correct, often a tune problem can trigger this code.

Exhaust is stainless is ok. Did not know that a bad tune up could cause this problem. Just had a tuneup about 100 miles ago. But it was running rough before the tuneup. And stalling. Thanks for the info. Ken
