Dear Scotty

I have a 2013 Chevy Sonic 137,615 miles on it I heard the car popping on the road while speeding up 2 times total falling acceleration and it started losing acceleration and than later popped and  gaining speed and the car has had a foul odor through the vents for a months I brought it to a park when I got done using it and the next day it could hardly accelerate and now it can’t accelerate at all I noticed it leaked a small puddle near the left front of the car and front center underneath and a little dripping further down the mid section of the car where pipe runs along and back exhaust pipe little dripping also left a stain on the ground now it can’t change gear tried changing the transmission fluid noticed old was low and slightly black burnt and replacing the spark plugs didn’t work I don’t know what it is and I’m stranded in Wyoming and can’t change gear or accelerate the car
