first run an injector cleaner through it .if that doesnt help get a lak off test done this will check the injectors for internal damage. you simply run pipes from each injector spill off run engine for 3 mins and check each one if spill off greater than 20ml that injector damaged. if all ok check rail pressure on scanner should be >600 bar on tickover.
