O2 Sensor Spacer | URO-SENS-SPCR

We apologize for the inconvenience you experienced with your engine's rough idle and the Check Engine Light not turning off. We understand how frustrating this situation can be, especially when the installation was done correctly. We would like to clarify that the website stated that the item you purchased is not 100% guaranteed to remove the CEL on its own. It works in conjunction with a tune, which will effectively address the CEL issue. We apologize if this information was not made clearer during the purchase process. To resolve this matter and ensure that the CEL is addressed, we recommend considering a compatible tune to work in conjunction with the product. Our customer support team will be more than happy to assist you in finding the right tune and any additional information you may need. Please reach out to our customer support team at Support@urotuning.com, and we will work closely with you to find the best solution to address the rough idle and CEL concerns. Your satisfaction is our priority, and we appreciate your understanding as we work to rectify this situation for you.

Hello Juan, As stated on the site there is no guarantee this will prevent a CEL from triggering. The only way to remove the CEL from coming on is with a tune. The spacer will pull the sensor away from the excess heat from the aftermarket downpipe.
