I have a 95 ford f250 with a 7.3 powerstroke that is missing on one cylinder. I did a buzz text and it was clear that injector 6 was not firing right. I changed the plug that goes into the valve cover gasket and the gasket and it still misses on that cylinder. I did an oms test on the harness from the icm to the valve cover gasket and it is all good. I'm assuming I have a bad injector. Or am I missing something. If it is an injector what is my best potion to getting it fixed? I am thinking of changing all of them and putting bigger ones in. If I do that what else will I need to change? I have an intake ,5 inch exhaust, gauges, and a ts performance tuner with custom tunes from kt performance. Any idea on cost? Thanks in advance for your help.

 

Pull the cover & make sure the solenoid is not loose first . You can measure the poppet clearance too . THe Injector solenoid s should ohm around 3.5. Did you look at the UVCH while you were in there ?Check the hold down bolts for tight & the GP's as well
