I'd start with the air filters as previously suggested. Try leaving your car out in the sun with doors open and let it sit for 30 minutes while you're in the garage (oops you're in OKC). If all else fails.......it is time to strip the smell off with Stripper Scent. It actually smells like one. I had a sample while in their store today and NO I did not buy it. This is a case where you can touch and not have to buy.
