GAAAAHHHH!!!! overfueling troubles.....

[umpkin]

hey guys, im looking for ideas, and solutions, lol

my car is costing me an arm and a leg in fuel, i.e about 10-12 MPG with normal driving (80% duel carriageway), i have a T25 running about 9-10 psi ish (dash gauge)

I have just replaced the fuel pressure reg, and is running at 36 psi as per the manual.

and have swapped the air flow meter with same results, when i went for MOT the emissions were high bout 5-6 %

any other things that could cause this, as my work is 10 miles away from my home, and i do 40 - 50 quid in fuel just for these 5 days.

cheers for any input.
