bp with egr valve

Festyboy,
How do you raise the NOX numbers when you are misfirring?
I would imagine the HC's would be high under those circumstances, especially with oil burning.

yeah i was refering to the HCs, but remember if it's a lean miss, you have excessive heat in the cyl causing NOX to rise. now, not seeing the condition of the plugs/valves hinders my diagnosis but i don't think i'm too far off.

Thanks all of you. I feel a lot better about my current motor passing because it does not foul plugs or use oil.
