I am having this same problem as well. Mine usually smells at WOT, or when going up hills. Its so bad sometimes, it makes me want to puke.I'm not sure, but i think the problem is that your engine is getting too much fuel, and its being dumped into your cat, where it burns up. This could end up buring a hole in your cat, which i've heard isn't very cheap. I'm getting my engine checked out tomorrow though. It could be a O2 sensor, fuel injector, or anything in the fuel system. I'll let you know what happens.
