I can't believe it'* a pulley thing.
There is plenty of fuel. WOT A/F reading is consistant at 10.7 which is on the rich side of the optimum 11.5.
When running normally the A/F is 14.7
When the KR occurs, the rpm is low and boost pressure is only just beginning to come on.
Boost thinks he found his KR culprit in a loose knock sensor connection. How could that be a likely cause.
Something about to let go in the trani sounds like an old wives tale.
If it'* gonna blow from wear it will take at least another 25000 miles.....it it blows from power, it will go BOOM immediately, spewing its red Dex blood out onto the blacktop.
Can I rule out faulty knock sensors by disconnecting them, temporarily.
