Car Shakes a Chugs.

Okay, I have a 2001 Kia Sephia that I got from my father. It has 47000 miles on it. The oil was just changed last month, and I just picked up a new battery. I don't think my dad kept up with the car because it was the orginal battery in the car.

I recently got stuck in the snow at the end of my driveway. I was trying to rock the car, and it was snow banked. I dug it out some and tried to get it out again but it wasn't working. I turned the car off because I didn't want to waste fuel. When I dug it out the rest of the way, I started the car, It started fine, but it started chugging and shaking. and the check engin light was on. I figured it was just overheated from trying to get it out, so I left it sit over night. When I started it the next morning, still the same thing. So I took the battrey out for 5 minutes hoping that it would reset itself. It stopped for a little bit, but started chugging again. I drove its fine when your driving, but when you stop, it does it again.

I also noticed when you have the heat on and your stop, the car doesnt want to move when your about to go. I had the pedle to the floor and slowly accelerates and revs very very high before it goes into second gear. With the heat off, it moves but still revs very high when it gets into second. The check engine light flashes when you drive.

The exhaused isn't pushing out normaly.

I didn't notice any lines pinched or kinked underneath the car where it was stuck, and no fluid is leaking. . Does anyone have any ideas? Thank you!
