[scorbad]

Hello,
I have a fiesta of 2003, 1.4tdci running on 3 cylinders,

the customer has changed its 4 injectors, without result,

after a little research, I found a wire cut on the beam injector 4, I repaired the wire, the motor started well, no gradation mode,

now the car runs great, but I have much against vibrations and jolts low REGIME,

the diag I have 4 default:

p0272 Cylinder 4 Contribution/Balance
P0266 Cylinder 2 Contribution/Balance
P0269 Cylinder 3 Contribution/Balance
P0263 Cylinder 1 Contribution/Balance

Were these new injectors or rebuilt? I only fit new, had lots of trouble with rebuilt.
