Message Recently dropped the cats among other uprgades, figured it was responsible for the light smell of fuel. Then this week, started noticing light gray smoke coming from my exhaust when I was stopped at intersections. Probably smokes slightly too when I am driving, just don't notice it. What caught my attention was a dip in MPG's from 20.2 last week to 12.8 this week. Burning fuel? Mechanic is looking at it in a few hours, just wanted to see if anyone else has experienced anything similar and what you found. Anything I might have him specifically check? He knows the car pretty well, but any advice I can give him couldn't hurt. These Z's are another animal.
Thanks
