I've been working on my car for the last week trying to troubleshoot a poor performance issue. I'm getting a rattle sound from a area around rear passenger coilpack. I unplugged the pack, rattle stopped. Plugged it back in rattle began again. Replaced coilpack with another one. Rattle noise came back. My car is running poorly and I'm stuck on what to do next.
