Hey Guys,
Before I start background on myself. Marine Mechanic, little first hand diesel experience. Pretty well informed on how diesels work etc.
95 f350 with 107,000 on it.
The truck has been running poorly the last couple weeks and I have not made it a priority to really figure out the issue. Finally took some time this afternoon to see what was wrong. Rough idle, poor acceleration, typical sounds of a cylinder not running properly. When it first started becoming a problem I could let the truck run 15-30 minutes of driving and it would be fine, then at some point the poor running condition would begin. At this point the poor running condition is constant.
Took the valve cover off of the driver side of the motor and started disconnecting the cylinders 1 by 1. I forget how ford numbers their cylinders as I work on mostly GM, but it seems there is no change in the motors running condition when i disconnect the second injector from the front of the motor. I am strongly leaning towards either the injector being down or possibly could I be dealing with a wiring issue? I dont understand why now there would be an issue with the wiring harness. Its clean, no cuts or any worn wires.
Does anyone know of a way to test for an injector being down other than what I have done so far? I wish I had a spare injector to swap before purchasing one because I cannot imagine there is the ability to return an injector once it has been purchased.
Thank you in advance for any and all help
Eric
