This demonstration guide answers one field question about idle control that has not yet recovered to governed rpm. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with voltage during idle-recovery after a load step. That reading separates idle control that has not yet recovered to governed rpm from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the idle-control solenoid as the primary path. If it is in spec, do not replace the idle-control solenoid just to complete a parts list.
Repair the failed system
The usual correction is the idle-control solenoid, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about idle control that has not yet recovered to governed rpm.
Stop before you make it worse
Do not disconnecting idle control permanently for "better power". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the idle-control solenoid is corrected, convert the visit to a broader diagnosis rather than stacking parts.
