The knock sensors are under the intake manifold, otherwise it would be the next step. I've got too many irons in the fire to not have the X running at the moment and would have to take it in to get those get replaced.
I'm hoping to find something I might have overlooked or not considered to get through a smog cert in the short term.
I replaced knock sensors on my daughters old Maxima this summer and it didn't resolve the fault codes or issues so I'm hesitant to jump to that as a fix here as well. She's now driving a slightly used Subaru
