It has become recently apparent that mmy EB series 1 Fairmont has extremly poor fuel usage.
I have the long range tank (80 ltrs) and i get about 400km from that.
This compared to my old CFI 3spd EA with a 68ltr tank which got 350km.
further to this, the exhaust pipe couldnt get any blacker if i painted it.
Now im aware that it could quite a number of things, so im wondering if its worth me just getting things like MAP sensors, etc replaced, or should i just take it to a mechanic to get it tuned and the timing changed? It has brand new leads and plugs, and is run on PULP. Ive run injector clean thru it several times and have inspected the filter, both of which are fine. so what else other then a mechanic do you guys recommend?
