Hello all. I am in the process of replacing a bad O2 sensor on my 2004 LT. It was getting bad fuel mileage,About 30mpg before a battery swap. I tried the TPS reset. Tried riding it to relearn. I kinda figured it was a waste of time. Cause I thought it's got to have a good O2 or it can't set correct fuel/air mix. Well neither worked. Still wouldn't idle. No surprise. Anyway. Been spraying the sensor base with Aerokroil since last night. Figured why struggle. Let it work it for 24/30 hrs. Sound like I'm on the right track?
