Clark C25CL:
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.

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.

Fact of the week

Before that, Congress generally had to authorize each bond issue. The debt ceiling was raised at least 90 times in the 20th century. The last raise occurred this year in June.
