Someone might have a solution for a problem I'm having with my XF ute. The engine in my ute was old, tired, and had a quarter mile time of, oh, probably around 2 minutes 37 seconds, give or take a few seconds allowing for my reaction times ...... Fuel consumption was pretty bad - around 180km per tank city driving.
I transplanted my newish reco 250 carby engine and auto trannie into my XF ute from my XF sedan. The engine is strong, and had only done about 10,000km in 4 years. In the sedan the engine pulled like a train, and trannie kicked down nice and hard. It was strong enough to leave a few V8's in its wake. Fuel consumption was terrific - around 6-700km per tank of petrol for freeway driving, and about 500 for city driving.
Accelleration is still as sluggish as ever, and consumption is only marginally better at about 280-300km a tank city driving. The carby was checked and is fine, air cleaner, plugs, leads, etc are all new. And the exhaust pipe still has carbon deposits all over it. Start-up is fine, but taking off the car splutters and coughs and takes off so verrrrrry slowly!
Can anyone suggest why my car, with new engine and trannie, won't deliver?
