Error Codes 0172, 0087

I've got a Clark with codes 0172 and 0087. It has a 2.4l engine. Its running rough and will surge at idle. Does anyone have any literature on this unit?
Any info on what these codes mean?
Thanks in advance.

EVERYBODY needs a little help sometimes.
Showing items 1 - 4 of 4 results.
If your fuel system is Juniper
fault 87--- fuel pressure too low
fault 172-- running too rich, fuel trim lower than expected.
check fuel filter
Regulator output to injectors should be 1600 -3000 millibars.
Clark upgraded the regulator a few years back to a single stage regulator, which resolved rough running, faults, coolant loss into fuel stream and hard starts.
