'13 Expy Limited w/130k
I get this weird vibration, rattling sound down in front of my feet mostly at highway speeds, at any sorry of incline, while the transmission is in a high gear. It used to get really bad, so I changed the spark plugs and coil packs at around 128k. The condition improved, but it's still there, but not all the time. There's no drop in RPM when it happens, and the sound remains even after an upshift. It seems to go away only after beginning to decline or by backing off the accelerator. I do have a loose heat shield that rattles even at low speeds, but this sound seems to be closer to the engine compartment. Think it's the heat shield? Or something else? I'm getting no engine lights and no codes. Thanks for any advice!
