[QUOTE="Fredkrueger100, post: 4096724, member: 24577"] [SIZE=13px]I've never heard of aftermarket cats causing damage to o2 sensors, but they aren't as reliable as OEM cats. I usually just use a spark plug fouler or delete the CEL in the ecu/PCM if it's an older car and cat replacement isn't affordable. HPTuners license for that car is $100 and you can delete the catalyst check engine light. Catalyst inefficiency CEL can also be triggered by a thermostat sticking and not getting up to temp quickly enough. The engine needs to be nice and warm to run efficiently and the secondary o2s need to be 600 degrees or so to work properly.[/SIZE] It’s gotta be water in it. It has never done it before I cleaned around it. My son said the car drove fine other than the light coming on. A friend of mine at work had his cats removed and a pipe welded in place and then had the code deleted by a shop here in town. It eliminated the issues he was having with his converters.
