Installed Cat Back Exhaust and now I have a check engine light????
I had a shop install a borla cat back and had no problems for a week. I have only driven it twice since then and it has been fine. I got into it today and I have a check engine light on. What are some possibilities for this? I am assuming an O2 sensor issue, but I could be wrong.

The cat-back shouldn't have thrown a CEL.
Take it to Autozone and get the code pulled. |
check your gas cap, it's not on tight.
|
for real......the gas cap...if thats it i will kick myself in the nuts....i will go check it now
|
can't be the gas cap. could be the gas cap.
you can go to an Autozone and have them pull the code to be sure... |

Or were you playing Jedi mind tricks again. :) EDIT: If you got the CEL as soon as you started the car, its the gas cap. Just give the gas cap a couple more turns and allow a few drive cycles to clear the CEL. |
