[Aaron Cameron]

Has anyone had this with their machine code 37 flashing with idle about 4000 rpm. Shut machine down over lunch was fine after lunch for about 100 kms then it started again. seems to come and go.

From the service manual.....

Fault code 37.....(ISC) Idle speed control valve stuck fully open.

Symptom.....Engine speed high when idling.
