About 200k miles, no noticeable misfire, no CEL, Cylinder contribution fault for cyls 2 and 6, but I think those are older codes. I haven't cleared them out recently (older b/c they are unrelated to the thumping and previously I had a healthy misfire, bad fuel I think)
I have a deep, hollow thumping noise that varies with engine RPM. It is most noticeable at idle, but I think that's because the road noise doesn't exist then. Definitely sounds like it is from the left side (drivers side)
Performance seems pretty good overall. Decent mileage.
Thoughts? I can probably get video of the sound. The sound is very noticeable and hard to miss.
