Sluggish Acceleration 2002 S80 T6
 

I cleaned the ETM, put in new plugs and ipd coils as well as redid the harness looming, and the breather box.

I noticed my torque stabilizer mount is shot to hell completely (the bushing) so I'm going to get one from Volvo to avoid the urethane ones sold elsewhere due to the vibration they cause. I'll also redo the trans mount at that time.

When I apply even pressure to the accelerator at about 2k rpm the needle goes about a half step up but then falls back to 2k and struggles. If I stomp on the accelerator I get the torque mount shudder but smooth tach to 3.5k forward..

Plugs were OEM Volvo and I checked the gap as well.
