hi all could anyone help my mpg has dropped drasticly im getting about 80 miles for £30 :jaw-dropping so around 23=26 mpg problems im getting on start up when cold its smoking bad but smells like a mixture of exhaust fumes and un burnt fuel, if that makes sense, also it is taking a long time to reach temp ie centre of gauge, i can start it up in the morning leave for about 5 mins on tickover then drive to work aroun 4 miles and its only reaching past the blue mark, ive had a new turbo fitted with the new oil breather etc, im thinking injectors and thermostat any help would be great:thumbsup

Sort of answered your own question, needs a new thermostat:thumbsup. Wouldnt worry about injectors unless it runs rough or is poor to start or smokes.
