so i went to work..
left the car out side in a cold weather for 11~12hours today..
(till about 3am and today was really cold)

and i started the car after work.. and suddenly
engine check light came on..

i got the inspection a few weeks ago.. and it was just fine.

can a cold weather cause this problem?

what should i do now?

 

Scan the code. Go to autozone they will do it for you. Most common Is loose gas cap.
