Code 522-655-1 Engine lopes

we are working on a:
Yale
GLP060VXEUSE087
B875B05005D
lift runs fine until you go to use the sideshifter or tilt, when it comes back to idle it lopes real bad like it has a radical cam in it until you rev it up. it is throwing a 522-655-1 code.
anybody have any ideas why its doing this.
Thank you

TSP Heated Oxygen Sensor (H2OS) Adaptive/Multiplier Circuit Signal
Outside Of Acceptable Limits

here are some possible causes of this problem:

- High secondary fuel pressure
- Worn fuel mixer
- Faulty Pressure Trim Valve (PTV)
- Faulty fuel trim valve
- Fuel quality (Very high butane content)

if problem persists after correcting the previous problems then replace the H2OS sensor

If problem persists after replacing H2OS sensor then replace ECU

this should guide you in the right direction :o)
