is there an easy way to check for a bad injector?

 

To me, the easiest way is use an AE hands down. Some have used one of those infrared thermometers to pick off the cooler exhaust port (not experience with that method). If it's missing, you can try to unplug the injectors one at a time until you discover the offending one. There should be no change in the sound of the idle when you unplug it. If you have more than one unplugged at a time, the truck will more than likely die. For the sake of discussion, what leads to you to believe you've got a bum injector?

 

how much is ae?

 

around 360.00 from riff raff with the ford bundle

Riffraff Diesel: AutoEnginuity Total Ford Enhanced Bundle

 

+2 on RiffRaff is the best place to pick one up & to have the Ford enhanced bundle to read/dianose PSD (PowerStroke Diesel) issues. It's amazing what you can do with one...takes a little bit to understand how it works and what menus to open to start different tests.

 

You just might have a loose connector, especially if you or someone else has recently worked on the motor. I would check to make sure all are tight before going any further. The connectors require a little a** to get them to fully seat.
