A while ago I asked your opinions for my 86 XF ute: bad economy, lack of grunt. And I'm going to ask again for suggestions. Found one problem was the rear disc brakes were gripping all the time, so that accounted for some lack of grunt, various horrible noises and 50km worth of petrol. However, I still have lack of grunt, and until warm, a coughing, spluttering engine on accelleration.
I had this problem with the old engine and trannie, and I thought that by putting in a new engine, and new trannie, it would alleviate the prob. No luck. Have tried various MAPS and ECG's, but still no luck. Plugs and leads have been changed, carby done, electrics checked, new fuel pump, fuel filter, etc etc. $6000,000 later .........
Can anyone think of a problem this car may have, which may not be due to engine or trannie, since both are new, and the same problems existed with the old engine and trannie?
I really, really, really, look forward to your suggestions!

I have an XC falcon ute with a 250 XF engine and the problem with this is it aint a V8.... how I regret that!!
To me they are a slug unless you spend $$$ on performance gear to get moving a little...not worth it IMO.
First of all i'm no mechanic so i'm only going from what i know. From what you described about coughing and spluttering when cold and it goes ok when warm it sounds like a carby tune problem. I realise you already done this but perhaps the carby is defective in some way.
I remember my mates XF Fairmont had a slight jutter when the car was warm.
Perhaps it's worth asking other XF carby owners if the carby is spot on in all weather conditions or the carby needs constant tuning.
Just some suggestions.

Umm by saying map etc I assume it's efi ?Though you say carb done?If carb fuel level maybe too high.
If efi the ecu been checked for fault codes? Then check things that control fuel. t.p.s/ h.e.g.o/ fuel pressure regulator.The pipe or hose going to your map is not fraded or leaking? And connected properly to your inlet manifold.. It will be simple things like that, that has been over looked..That has been done on change over or was there before ??
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
