These cars really need to go to a delphi agent if you want the in injectors sorting .
Even if you buy recon injectors then they need to go on a delphi machine to have new codes generated or they wont last long .
I've got a mondeo tdci 130 and thats got to go in and have the injectors looked at , it has done 148k tho
You got to be so careful with the fuel system on these cars .
Good luck
