the other day I was driving my truck and someone said I had an injector knocking.... is this even possible to know by just listening to the motor run???

this is coming from someone who drives a ford not a d-max

If you were accelerating you may have a clogged filter or air leak in the supply side of the fuel system.

PM for more info.

yeah i hear u there I just replaced the fuel filter and the thing runs like a dream but just curious if anyone knew of a diagnoses for this, if there is anyway of telling if your injectors are working properly????
