![]() ![]() This morning was cooler and damp, and no such buzz. I swear it didn’t make that noise until I hit ~900 miles, but now a “cold start” when it’s warm out, it buzzes.

Since the engine noise isn’t consistent, it leads many owners to be concerned and left with the impression something is faulty. This is a fuel injection characteristic caused by the High-pressure common-rail with a fuel pressure of 1800 bar and fuel injectors operating in split-shot mode. ![]() The T6 model Ford Ranger emits a buzzing noise at low RPM when operating temperatures are low.
