Re: 2000 6.0L runs rough and stumbles

I just figured out mine....I tested the injector harness and was getting the noid light to light up but it was obvisous the cylinder was not firing, header tubes were 'cold'.
ended up having 4 of the 8 injectors not firing, I replaced those not squirting with spare ones and it runs good now.

I pulled the fuel rail up and had my son turn the key and watch to see what injectors are firing. and replaced them and run test again. it can be a little mess so you might take a little more time and catch the fuel being squirted out....
