Anyone any ideas why my fuel consumption is so high. Ive got a standard 115pd and im lucky if i can get 40mpg around the doors. I used to easily get high 40's around town and high 50's early 60's on a run. I know the cold weather doesnt help but when the mfa reads 33mpg i think something is up. Ive noticed recently that car seems to have a miss but only when just started. Recently replaced the MAF with a genuine VW jobby. Could this be faulty? Car still seems perky enough although on a recent trip to scotland I had my foot planted to the floor on a slight hill and i was struggling. Any ideas would be greatly appreciated.
