Check the rubber boot going to the TB. They crack over time. Easy to
repair with RTV sealant.
For some reason, thought your post suggested you guys are located in
Canada. So I checked Bens web site. These parts are located in
Montreal Canada, but may be worth considering. (used parts. Scroll
down to the 1.9 stuff):
http://www.benplace.com/parts_sale1.htm I've never been to Bens shop
(would be a bit of a drive for me!) but from what I've read, his
reputation as a mechanic and restoration expert is excellent.
I don't know Digijet much, but my guess is that if there's severe
vacuum leaks, the engine management might be overcompensating (riching
up the mix) which might explain part of the poor gas mileage you're
getting.

There seems to be a leak in the shaft of the Throttle body-- we switched it out with another ( used) and it too leaks around the shaft and has a poor fit between the butterfly and the housing.
