hmm they're not old so no need to change them.
I supose these are the readings on petrol not LPG?
I hope someone will be more helpful.
Here are the main diferences betweet our reading
B1S1 and B1S2 on my car both read as rich
Ignition spark angle is way different (mine being 41,6) although I think yours is better.
Knock control on mine is ACTIVE
Ignition Retard Knock Control on mine all read 47

Nothing to worrying with that lot of results !........is the cambelt timing all ok (not a tooth out?).

As for the lambda signals, the absolute voltages are not overly important, its the fact they are in closed loop control and toggling between lean and rich that is key.

If the bottom end was worn you would expect the HC levels to increase and not the CO

Marks did you mean mine or mark readings about the cambelt timing?

Marks......where are your readings?

[mathewst]

Aha ok sorry I just posted a few readings during this post.

Cambelt timing check this weekend i think.
Cambelt was changed when the HG was done, although we used the cam locking tool.
Would the timing being out cause it to run rich and how does the mechanics of that work??

I'm just trying to understand this as i am an I.T person and not generally mechanically minded.

for a little theory

That guide is really good, thanks for that
Going to check timing this weekend, it's a matter of lining up marks and notches if i remember rightly.

Following another similar thread on high emissions, i checked my exhaust manifold and it has a hairline crack in it...
Could this be the culprit?
