hi mondeo running bad i am leaking on one injector lots of black smoke etc.
so i bough the formidable F so i can my injector code and they are as they are printed on the sticker. but after closer inspection the code stamped on the injectors are all different apart from one thats on the sticker. am i correct i saying that if you replace injectors you need to reprogramme the ecu to the injector codes on the injectors rather then keep the old ones

my sticker shows

cyl 1= A841F3613A3DB24D code on injector is FC5A8******
cyl 3= 2c4a03a**** code on injector is 0c520c22c27****
cyl 4= d04e53e*** code on injector is d04e53e6
cyl 2= c445d36 code on injector is c445d36 (same)

and the code on the stick match what i read on the ecu

please can someone help it looks as though someone replace them and may not of coded them to the new ones or do you keep the old code really appreciate some input
