Thanks Doc.

Well, my car does have a pretty good exhaust leak somewhere in the exhaust system. Its not loud and I cannot smell exhaust while driving, but I can hear it splutter (like a leaky exhaust sounds) when it idles and I am outside of the car and wondering if this could have something to do with the airflow to the sensor or something?

I have never heard tell of it before, but just wondering.

I need to get that leak fixed soon anyway.
