Hey-

Now that all the major car-threatening work is behind me, I've started to actually notice what it's like to live with the 146.gif on a daily basis; and something I've found is the reasonably rubbish economy.

I'm rocking the 1.8 CF2 and it's giving about 63 miles to every 15 litres of fuel around the town (and that's not supermarket fuel). That works out to be a fairly crap 19 mpg. I'm astonished by this as I would have expected a bit more.

Now, don't get me wrong- 'what do I want from a 17 year old Italian car, with 104K on it..?'

well, I want it to run well, I suppose. The economy doesn't bother me really- it's not a deal breaker; I don't find myself wondering about a buying a Vauxhall Corsa or anything- but I do wonder if its indicative of 'something'...

The fumes do suggest that it runs a bit rich, but it doesn't use oil at all, or smoke or do anything strange- indeed it's the best running car I've ever had!

But I wonder what I'm missing- it got though the MOT no problem, for instance.

I wonder, in terms of 'replaceable parts' if swapping the Lambda probe for a brand new Alfa Romeo one (at some expense, I daresay) would make a difference?


What d'ya think, team..?

I'd expect better than that. I manage 30-33 mpg on a 2.0l with more miles.

Yes Lambda would be my first guess but seeing you passed the emissions I'm not sure!

Thanks for that, lads

I've got the first service, under my ownership, coming up on Monday.

spark plugs are included- I'll look into the Lambda cost in the meantime

well,

new plugs- 90, and a Lambda sensor 77 later, the car is serviced- amongst other things too, of course.

So the watch on fuel economy begins!

thankyou!

sitting in traffic for an hour and a half yesterday can't have helped, I suppose...

maybe it'll be the 'next' tank, before I find out...


it certainly seems to 'slightly' more initial-response, when pulling away...

Get the Fiatmultiscan diagnostics on it to see if something is a miss. I only ever had horrendus mpg when my 147 ran on 3 cylinders. One of my ignition coils packed in. Was literaly getting around what you are getting.
