My God, you're a miracle worker! All the lights went off. Should I still go and check the codes again or am I good to go? Thanks
Expert:  Skyvisions replied 11 months ago.

There will not be any codes and the lights are out and the codes are cleared. For now you're good to go to the problem reoccurs.

Customer: replied 11 months ago.
Crap, the lights just came on again. Any idea of what those codes are to get fixed at the dealer? Thanks
Expert:  Skyvisions replied 11 months ago.
Can you get the code numbers check before you drive it too long to see what codes come back first?
Customer: replied 11 months ago.
They are on the beginning of the email string. They've been off all day and came back. My gas mileage went way up!
Expert:  Skyvisions replied 11 months ago.

I saw the original codes did the exact same codes come back this time since you cleared the codes?
