Cylinders 1,3,7 low injector circuits ficm checks out other possibly. Causes

 

Bad harness.....

 

What harness and where is it located.also I just added an egr delete kit. Appreciate any advice.

 

The ficm harness that runs to the injectors. If you got prob after doing the delete recheck your injector plugs to make sure that are clipped in good and the connectors at the ficm too. Also check and make sure u didn't bend any pins on the injector plugs.

 

i had the same issue on my f350. millerboyz knows what he is talking about thanks miller!
