As i'm going down the roads, my Trac light, ABS light, and my tire pressure light comes on. And when it comes on, I can feel my steering stiffin up alot. Any idea why this happens? (Lights come on because the sensors are cut on both front wheel bearings). Also, would gas milage be related to these sensors for some odd reason? Becuase right now I went 215 miles and have less then a 1/4 tank. (no codes and mostly highway driving).
