Thanks for that post - i'm just about to fit a Zavoli to my 760 (might have to find a Lambda sensor and fit it as well!
) so that information is very handy!
Glad also you got the problem solved, it sounds as if maybe the original installer set everything to run a little lean resulting in this fault a bit down the line. Would probably have been picked up on a routine inspection of the LPG system though as calibration wanders throughout the life of anything.
