Sooo I threw a Check engine light today... It seemed to come out of no where... I drove to lunch today... parked the car, came back out a few hours later to cash my check and it was on... Car doesn't drive any differently... But after being shut off and coming back on throughout the day... its still on... any idea what kind of bullshit I might be up against?

 

Probably want to get the code read. Can't really diagnose it if we don't know what the code is. You can get it read at auto parts stores like autozone for free.

 

Did you check to see if your gas cap is on tight?

 

Its an HO2 sensor.... 150 bucks.
