I recently installed a spoon exhaust to my S2K but while I was driving along, the check engine light came on....

Any inputs on how I can eliminate this problem...thanks

 

Somewhere along the installation you dicked up your O2 sensor. I would first try to simply reset the onboard computer. May have set a code due to the "differences" between old and new. Check the FAQ section here on resetting the "computer" or "OBD-II System". If the light reoccurs then you need a new O2 sensor.

it's the O2 sensor.

But, it could be completely unrelated and you just happened to throw the CEL after you installed the exhaust. It would help to pull the code.
