Hi all, not sure where to post this under. Had the check engine light, traction control light and flashing cruise light come on today. The check engine and traction light are solid with the cruise light flashing . Runs fine no power loss or smoke or leaking . I did plugs , air filter and serpentine belt about 75 miles ago. No issues up til now with the changes. Could it be something with having the battery out to do the plugs? Any help would be appreciated. Thanks Ron.
