rough running om617

ok everybody i have a 96 jeep cherokee with a om617 turbo motor.when i first picked it up it ran pretty decent but now its getting tougher to start and it has a engine miss that seems to be getting a little worse. it has an external elcectric fuel feed pump which i have no idea what pressure it puts out but flow is good.i have adjusted the valves and it didnt help. i have not checked timing yet.but i did notice the rack dampener bolt was screwed all the way in so i loosened it and no matter what location its at it dont help.the alda has been removed but wasnt done by me.im curious if the rack has been removed as well?how would i check for that.the dampener bolt is the old style and i can push the little pin in by hand.but the miss seems to be the worst just barely off idle maybe 1500/200 rpms.just wondering if u guys could point me in a direction of where to start.the motor i have not check compression on but when it was swapped supposedly had 425-450 psi on all 5 cylinders.
anyone that cares heres a pic
