Unhappy 85 380 se low speed miss.....HELP

my daily driver, an 85 380se, developed a low speed miss, goes away above idle. checked the normal things first, plugs and wires, checked cap, rotor, all are not very old. then i checked fuel flow to the injectors. no pressure at number 8. cracked them one at a time and had good pressure except for 8. it just trickeled. what should i do??? im sure this is my problem, pickes up pretty good above idle. thanks for any help

Unhappy fuel distribution block- anyone ?

i traced my problem to weak fuel pressure at number 8 at the distribution block, all have pressure at idle except this one. what should i do, i may have screwed up cause i took this apart, thinking it would be easy. thought it might have trash or something in it, but i cant find parts to rebuild this thing. everyone wants to sell me a reman. is there any hope??? has anyone tackled this thing??

rebuilt unit

i found a rebuilt unit for 395 plus your core, haller engineering in ca. everyone else wanted 500. that will fix mine i hope, jacob gave me tech advice on the phone and we determined that mine was bad after i had taken it apart. i had lost my #8 cylinder, he said it was a common problem.

losing # 8 is a common problem ? or this unit going bad is a common problem?
my car was fine until the head gasket went and the car sat for a few months while I rebuilt the head etc.
The car runs rough (missing)
no or LOW fuel pressure at the lines coming off the unit.
I thought it was all 4 on the right side?
(this is the side I did the work on)
