This pinging is driving me crazy. I have replaced my knock sensor and the EST module. I had Bumper to Bumper scan and check each of the sensors. Each sensor is working properly, right where it should be. However, I'll be damned if I'm not still getting the ol' death rattle. It's very difficult to tell if it's an exhaust leak or pinging, but I'm pretty sure it's knock. I don't know where to go next.
