Either your cat is not converting or you're producing too much NOx due to lean mix/high combustion temps (ignition timing off?). Try a new O2 sensor, or at least test your old one. Or try some of that stuff you add to your gas tank; maybe you'll squeak by. Replace your thermostat and check your engine coolant temp sensor for idle problem. -- :-) "Karlheinz G.
