Injector and Fuel System Care
Injector and fuel-system care for smoky, rough-idling diesels, paired with a calibration check when the ECU is part of the fault.
Smoke and a hunting idle are often a fuel-system story, not a reason to write a stronger map. We look at injector trims, rail pressure, and how the engine behaves at idle before recommending care.
Fuel-system cleaning is for deposits. A cylinder that is miles out on balance needs the injector off the engine. If a previous file is making a tired set of injectors worse, we can return closer to a sensible calibration once the hardware is honest.
