Thanks - as I thought, throttle position should be 10% give or take a small margin - so 9% is spot on.
The Timing Adv is, I presume, the same as the SPARKADV figure I see on my scanner?
15 is what I'd expect it to be at idle - which is why I questioned the 22 or 23 figure I'm getting - it seems a touch on the high side to me.
It will be interesting to see what new plugs do.
