landar Posted November 4, 2010 Share Posted November 4, 2010 What code(s) are you getting? Is it a main (as you imply) or sub oxygen sensor? Depending on sensor location, it could be a problem with the cat and not the sensor itself. And just curious, how many miles are on your car? Symptoms might be lower gas mileage and/or failed emissions test. It is not as serious as a heart attack but more than a toothache. :) Welcome.

Which code(s) are you getting? See this link -> http://www.lexls.com/tutorials/intro/codereading.html Quote Link to comment Share on other sites More sharing options...
