Exhaust smell
So several weeks ago I started to smell what I thought is exhaust coming into the cab area. It only happens when the heat is on. A friend of mine said he doesn't smell a thing. I did get a check engine light and it turned out to be the O2 sensor. That has since been replaced by the speed shop that I use. I had them check the vehicle extensively and both mechanics said they don't hear or see any leaks anywhere. They had it up on the lift to replace the O2 sensor, checked EVERYTHING and swear that there are no leaks. I still smell the odor at times though. Any ideas or suggestions?? Thank you.
