Default Strong smell from exhaust while accelerating.

My wife was driving behind me today, and while at the red lights she said she would get strong whiffs of an “old gas” smell as I accelerated. She couldn’t smell it while I was idling, and I didn’t smell it at all in the cabin. Any ideas as to what it could be?

Is it possible you have stale gas then? Run till empty and refill.

Not at all. It has fresh 93 octane with Lucas Fuel Injector Cleaner.

Fresh to you but if the station has older gas, you may get some of it. Also she could be smelling that stuff you are adding. I know stabil makes the exhaust smell funny
