Hello Jeff, my name is***** for the question. If I am not online when you return please give me some time to get back to you. Start by looking under the drivers side of the dash and see if there is a small device plugged into the data connector right under the dash. If there is remove it. If not then you have one of two issues. You either have a failing catalytic converter or someone added this program into the computer. It would have to be reprogrammed to repair this. Is the check engine light on?
