An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

I started the car and was standing near the drivers door with the car running. The fumes were not gas but I felt like they were making me high. I am thinking they were probably from the converter. I am in a wheelchair so I can't get under to look. I plan to take it to get it checked out.
Smelled gas low power then o2 sensor went
Smoke coming from the back of my 2004 aviator. Definitely more than gas. I'm also burning through fuel too fast. Any suggestions? I did notice a small exhaust leak under the truck in front of the catalytic converter.
