This problem only occurs when the windows are down so my guess is it's from somewhere in the engine compartment, but it is definitely not the same smell as a bad cat converter. It's almost as if someone left a Windex bottle in there and it heats up occasionally but that's not the case. At least pretty sure.
Has anyone else experienced a similar smell? And for clarification, 2003 V8. Thanks

It comes from the exhaust just like the sulfur smell. I have experienced this a few times with the rear window down and me gunning the accelerator, even worse when I am going up a steep hill. I have never experienced any smells if my rear window is up. Somehow it is a product of the combustion process and/or the attempt at "cleaning" it from the cat converter.
Sulfur, amonia are somehow byproducts of the combustion process and I'm sure you could find a very technical/chemical explanation if you searched hard enough.
