There's an interesting thought. No, the car doesn't have a lambda system, no cat.

I did recently tweak the EHA as outlined in previous posts and it did improve the low speed nehaviour now I come to think of it.

Not having any electrical feedback to work with, I've adjusted the idle mixture in the past by squirting carb cleaner into the intake and adjusting based on that. I think I'll give that a go again.
