84 300SD rough idle

Engine idles with a miss that goes away at 1000 rpm. Pulls good from 1000rpm
Have replaced injectors, timing chain looks good. Pulling the fuel line from each injecter causes a diffinent miss. Fuel filters new. Ran good till 1 injecter frooze.

Found problem. I replced the rack adjustment bolt, reset according to the instructions you include with new bolt and vola, smoooth idle. Thanks again.
