Rich smelling exhaust?

[mikemk4gti]

 Just picked up my 90 mk2 8v today and Ive noticed that the exhaust smells very rich, is this normal or does it need some adjustment? On the 100 mile trip home it averaged 40.8 mpg on the mfa so I dont think its overfueling?

The mfa's do lie best to fill it right up and then do say 100 miles, re fill and work out mpg from there.

yeah thought it probably wasnt too accurate, but did 100 miles on less than £20.

They are very good on fuel on a run mid 40's if driven sensibly is not uncommon.

Good good, Thats what I like to hear!

Yours is a Digi so they are not adjustable, try a new temp sender.

There's a guide in the how to and it says about adjusting the CO level, is this not it?

Well yours is a digi so I don't think it is adjustable as it is controlled through the ecu.
