This TSB article is being republished in its entirety to correct the part number for the 7.5L engine injector assembly.
ISSUE:
A stumble or rough idle condition may be caused by lean fuel flow resulting from pintle deposit formation on non-deposit resistant fuel injectors. These
non-deposit resistant fuel injectors are susceptible to pintle deposit formation.
ACTION:
If service is required, install deposit resistant injectors. These Deposit Resistant Injectors (DRI'S) are acceptable service replacements for non-deposit
resistant injectors that exhibit lean fuel flow. Refer to the DRI Replacement Chart for correct parts usage.
