Hi, I'm wondering if anyone has had a similar experience with this? I have a 2000 Insight at 65000 miles and I've been noticing that when I accelerate or go up a hill at 65 mph, I smell something like exhaust. It's not a strong smell, but I can definitely smell the difference. I've been told that it could be the catalytic converter, but my mechanic hasn't been able to detect any problem. Any suggestions?
