hi all, hope someone can give me some help, well i have a 2002 mondeo tdci 130 (fmba engine), starts fine everytime and drives through 1,2,3 gear fine even if i boot it a bit, but if i try and boot it in 4,5th gear the engine seems to loose boost at about 3000rpm and the glow plug light flashes,if i stop the car and restart it,which it does straight away its fine til it comes under load in 4,5th gear. egr valve has been cleaned and blanked off. ive been told its not the injectors as its starting fine and running fine under normal conditions even if it drive normally in 4,5th gear its fine,just under load it does it,really annoying when trying to over take. ive done a dtc check on the car and it shows up no stored faults. any help would be appreciated,thanks steve
