Question about 2001 GMC Yukon
My 2002 Denali has always done it with the heat on at idle. I run the heat on recirculate and the exhaust smell disappears 100%.

Get that checked asap. Could be a number of things.

Check under the hood and make sure there are no fuel lines leaking.You should be able to smell it.If you don`t know what to look for the take it to a garage or your dealer and have them look it over.It is not safe to drive if you smell fuel while driving.It could cause a fire under the hood.Good luck.
