I picked up my CSE auto with a great looking exterior and interior with only 85K miles.Had a great ride for about 40 miles miles and suddenly, after coming to a stop, the car would barely move giving it full throttle. After a while the gear would catch until I had to remove my foot from the gas. This went on until I came to a hill and could not make it all the way. After parking it for about 2 hours, I tried again and after about a mile and anothter small hill, it would not go any further. Luckily I was a block from home. Anyone have a heads up on what my problem is and what it's going to cost?
