Ride: 2010 FG XR6

Location: Pahiatua
New Zealand

My FG is having a rev hunting issue from anywhere between 1k and 2.5k. Jumps anywhere between 250 to 1k revs. Hesitates to accelerate too, doesn't have a high idle or a missfire. No lights on the dash and no major codes. Have tried new maps and 02 sensor. Tried to the best of my ability to spray the intake with ether and propane.

Any ideas would be appreciated.
Cheers

Maybe the PCV valve on the rocker cover.

A malfunctioning IACV can disrupt idle control and cause erratic engine behavior. Clean or replace the IACV as needed to ensure proper idle control.
