i was driving my car today and it felt like i had a rearflat (kinda fishtailing when i turned and slowed down quickly went i let off the gas) but i got out and i didnt have a flat. it smelled like burnt plastic like something went out, but i dont know what it was. any help?

 

Could be alot of things ... jack the car up and start looking feeling.

 

Maybe you ran over something plastic that got caught up under the car, then came off before you stopped to take a look.
