Interesting to see that I'm not the only one experiencing this. Is your experience identical to mine? Perhaps it's due to a cold start and too rich of a fuel/air mixture? I do sometimes notice the smell of unburned fuel if after a cold start. The smell goes away after the CATs warm up. I wonder if my fuel pump is going...or maybe a MAF sensor cleaning is due for me?
