Hi fixit, thanks for the replies.

I haven't checked the timing although it's an inconsistent surge at idle transforming into a miss at higher rpm.

As per my reply to Big Harry below, I unplugged the AMM and it ran better so common Brickboard Wisdom tells me it may be at fault.

I'm curious to know how/why these units fail when there's no obvious problems—IE stuck air flap. Maybe at one time the air flap was stuck on ... who knows?
