Thanks for the quick reply. Have just bought a new ICV and seen how it responds to 12v - nothing like the one fitted to my car - so will fit that this weekend and keep my fingers crossed.

Yes, getting current to the ICV, 12v at KOEO, haven't tested with engine running though. From what I've learned in the vast tract of 300e idle posts, when the engine's running this should be 6v with a 50% duty cycle (not sure exactly what that means yet but no doubt I will shortly).

Will now go looking for EHA current info for adjusting the mixture. If anyone can post or point me in the right direction to find this info, be much appreciated.
