Bad O2 sensor
Help, please! Any one have ideas why my LT4 is eating up one O2 sensor? I have had to replace the same one 4 times in the past 2 years - the last two this summer. It comes out covered with black soot-like material. Black smoke comes out the exhaust pipe on that side as well. Thanks for any ideas!
