So, I've got a funny 'problem' that doesn't bother me as much as it does my wife.....

Here's the scenario: I'm blasting down the freeway, foot in it good, everything's grand. But when I back my foot out of it, we get a powerful smell of exhaust.... that permeates our clothing... and makes me smell like I'm the "real-deal"... but my wife hates it.

I figure it's got to have something to do with the EGR / Air Pump system. ??
Any ideas?
