I notice the telltale smell of a rich running engine when I pull into the garage after a drive. I don't think it's a major problem considering there's no black soot coating the area around the exhaust outlets like I've seen on one thread here.

In terms of possible symptoms, the only other thing I have is a slightly lumpy idle.

Next step is testing the O2 sensor. I hope the thing isn't rust welded in place.
