Cm870 jake issue

[Rig Wrench]

Currently workin on an cm870 tat I'm havin issues with the jake rockers, cylinder 1-3. This is a 3 solenoid system. Cylinders 4,5 and 6 work perfect. Cylinder 1 just seems to bounce back and fourth, no noticeable change in anything. Number 2 works perfect, cylinder 3 seems a bit delayed, but its acceptable. So far I've tried new solenoids, new rocker shaft, swapped jake rocker with number 2. All with no improvement, I even ran the engine with no solenoids to make sure I was getting good oil out the ports. Not that I had a way to measure it, but it seamed to flow the same as number 2/3. Any help is greatly appreciated.
Thanks
