Juddering Focus mk2 Tdci

[andybr]

Hello

Have a mk2 focus tdci Engine code KKDA

I have a very apparent engine judder and poor idle....sounds like its only firing on 3 . 

I looked at the injectors and cyl 3&4 look like new injectors, i used a long screwdriver to listen to all injectors when ticking over and the new injector are ticking nice and loud and tick very fast....however number 1 and 2 look like old injectors and appear to be ticking very slow and quiet. injector one sounding very quiet.

injectors are 4M5Q-9F593-AD.

Would this be a good indication that i have 2 faulty or blocked injectors.

i have seen injectors on eBay with the 4 digit codes starting with a 1 but my injector numbers are as follows

51980 - fg19
51976 - fg19
51984 - fg19
51988 - fg19

Would i be correct in thinking that i could get any 4M5Q-9F593-AD injector for the KKDA regardless of codes and also without the need for coding afterwards. 

 

Many Thanks
