Recently, I noticed on cold starts in the morning or after the car has sat for a long period of time, the idle is a bit rough for a few seconds, and there's a sweet smell like maple syrup coming from the exhaust with a decent amount of white vapor/smoke that goes away after the idle smooths out and I drive the car about a block's worth of distance. I've just crossed 19,000 miles.
A quick internet search for "sweet smell from exhaust" points to coolant/antifreeze being burnt in the combustion chamber, obviously bad. There's been no increase in engine/cylinder head temperature on the gauges. And, even though there hasn't been a decrease in performance and the car drives fine to me, I am concerned. Has anyone had this issue before? A trip to the dealership is in order for me first thing in the morning.
I hope it's nothing too serious that can't be taken care of. Staying positive.
