Tech Tip: Ford 7.3L Powerstroke ‘Cackle’ (Noisy) Injector

Some vehicles may experience a misfire or “cackle.” The injectors in the 7.3L diesel run off of the high-pressure engine oil pump. The number 8 injector is the farthest away from the oil pump, causing a filling problem, which may result in a misfire. Ford replaced the number 8 injector in some vehicles as needed with a different injector to solve the problem.

Tech Feature: Servicing Diesels in Your Shop

Is there a diesel in your service bay? Maybe not now, but there definitely will be in your future. You’re going to see trucks as well as SUVs and passenger cars.
