....setup the engine perfectly!

Both banks balanced, and everything is great apart from running very rich at idle, and very first part of throttle application causes the revs to drop (and sometimes even stall).

Has anyone tried these:

Would this help in any way?

Cheers.

Yes I have them but not sure they will fix your problem.

Are your lambda's working properly?

I think they are. Recorded a short vid, I tried to show the rev drop a couple of times (first one at about 4 secs in), but it doesn't really come out in the vid. Set the other half's car alarm off though ;-)

Throttle pots are both new, but one does seem to be jumping about a bit, although I seem to remember something about this being more to do with the android app?

Impossible to tell from that as the left hand side is jumping about so much.

Do you have a multi meter to test the throttle pot resistance, they should be the same on each side. Test with the ignition off and set the left to match the right hand side TP as viewed on the app, set with the throttle closed and then check at different throttle positions that you get the same reading on both sides. Do this testing with the throttle pots disconnected.

I do have a multi meter. Which of the three connections on the pots should I be testing across, and should the readings be exactly the same/what sort of variation is 'acceptable'? Many thanks for your help so far!
