Limp modeNo

P2C60 is the minimum-limit code for injector B on cylinder 8, the last cylinder of a V8 and the end of this code series. Its A-side twin P02DA is documented by GM for the L5P diesel and by Land Rover for a 5.0 V8, but the B version has no public manufacturer source at all. The physics are the same as on the other cylinders: the learned correction has shortened the pulse to the floor because this valve keeps overdelivering. On a V8 a dripping injector on cylinder 8 often shows up as a rough first few seconds after a hot start, sometimes with a misfire record for cylinder 8 (P0308). Under both Ford and GM numbering it sits on bank 2. CARB 1968.2 (e)(6.2.2) requires the check.

Likely causes

Injector B of cylinder 8 leaking at the seat and adding fuel after closing

Replacement injector of a different flow rating or not matched to the engine software

Old learned values not reset after injector or software work

Supply pressure on this injector set higher than the model assumes (regulator)

Symptoms

Check engine light
Often nothing else noticeable
Long hot start or rough first seconds, possibly misfire on cylinder 8
Possibly fuel smell or higher consumption
