Hey I dont know if this is common but I've had a cel on since the day after i got a catless midpipe and then today for some reason it turned off. It's been on for maybe a month or so and then today when i turned on the car it just went away. I think it could be related to the outside temp because it was 51 for the first time in a while here in va. So any thoughts, explanations or ideas?

 

it might depend on what specific CEL it was, did you check it?

 

no i dont have a scanner tool to check it out

 

Sure, the light goes out to make room for newer, possibly more important CELs.

The car will still fail an emissions check, due to the stored code.
