Q4: Why is my engine running rough or smoking after replacing these injectors?
A: The 145-9360 is a Hydraulic Electronic Unit Injector (HEUI) that relies heavily on engine oil pressure to function. Common post-installation issues are usually caused by:
-
Trapped Air: Air inside the high-pressure oil rail can cause hard starts or rough idling. It typically clears after running the engine up to operating temperature or test-driving it.
-
Incorrect O-Rings: A torn or improperly seated cushion/external O-ring will leak actuation oil, causing a drop in injection pressure or fuel dilution in the engine oil.
