Engine load/ smell

[Craig Paquette]

Any time I put my GMC Denali under a load like going up a hill or step on the gas, you can smell the engine and I don't know why this is or what it could be coming from. I have had all fluids changed no change, and it doesn't smell like burning oil but I definitely don't trust going on a long road trip with it running this way. Has anyone had this issue or is having this issue? 07 all wheel drive GMC Denali.

define smell the engine?
exhaust smell-fumes
coolant smell
rotten egg type smell-sulfur like
burning plastic smell
any of those would mean either a exhaust leak, coolant leak, catalytic converter burning up or electrical short.
only other option would be burning oil which you stated it isn't.

Welcome Craig! Does it smell like fuel or exhaust? Has your mileage decreased recently?
