i was getting my coolant flushed and the car was warming up for about 5 or sao min and while walking around my car i notices a big of moisture on the floor by my exauct. it was like little puddles that formed with a little black towards the center of each drop. almost the way oil centers in water. anyway the guy said its carbon and im probably running rich i was curious as to if anyone else noticed trhis with their cars.

Water is a byproduct of combustion. On cold days, a lot of cars will spit out water from their exhaust while the engine and exhaust is still too cold to fully vaporize it. Although I have never seen this on my FD, I'm sure it would happen too under the right circumstances.

I've seen that a lot, was it a humid cold day? I wouldnt worry much about it
