Rough running and misfire
A worn or sticking injector sprays unevenly: the engine knocks, misfires or idles rough. A cylinder cut-out test finds the bad one.
Smoke and fuel use
Black smoke and rising fuel use point to dribbling nozzles. Replace injectors before they wash the cylinder walls.
Hard starting
Leaking injectors bleed fuel pressure back and make the engine crank longer, especially when hot.
Fitting tips
Fit new copper washers and seals, clean the seat in the head, and torque the clamp to the engine maker's figure.
