Hey I just spent 2 days putting in a rough county 3 inch kit and 31/10.5/15 tires and I never had a problem with the check engine light coming on before but today after the lift was put in the check engine light came on not an hour after everything was installed anybody know what this could be? thanks.

 

You may have accidentally bumped a sensor or something when working on it. Take it to an auto zone and get the code and then start from there.

 

Hey thanks had it checked out turned out to be an o2 senser gone bad thats a relief! appreciate the input
