Plenum pull will be the next step.
This problem first showed up sometime after my last plenum pull just before Carlisle.
Code 42 started showing up a month after the Carlisle trip.
Sometimes to won't set for a few days. Other times it sets several times a day. No real pattern.
All cables checked, knock sensor and O2's replaced.
Code shows with both stock chip and Mark's chip.
Last things left are DIS module (I have a spare) or ECU (no spare - reason for needing internal schematic).
