If they are shot...and the motor moves enough...downpipe can come in contact with the sway bar under heavy acceleration...giving the knock sensors false readings.

As well, are you using 91+ octane?
Just an update, it was in fact the trans mount. Now the most knock I see is 3, should be able to tune that out next week.

Thanks a lot,
Joe
