The more I read, the more this comes up. Some people say adjusting the TPS helps, but I'm fairly certain mine reads within acceptable limits. I'm going to get the car in the air later today to check things out - specifically the driveshaft and halfshafts.

What has me shitting bricks right now is the metallic "thunk" I'm getting during these on/off throttle inputs. Experience tells me the differential backlash is off, but I was ASSURED by a transmission/differential shop it was okay. My only other theory is that this noise is always around and that it isn't until after installing semi-solid mounts that it becomes audible.
