I've had a CEL on for about 2 weeks already (i'm not sure if this has anything to do with it.) It was driving fine until today. I drove it in the morning and it was fine. I go back outside 2 hours later and the problem started. The car is sputtering and the exhaust sounds like a lawn mower now. And when the car is in reverse (when i was trying to parallel park) and it was sputtering a lot too. Anyone know what's up?

 

What code ya throwing?
