In this past my Maverick starts to idle a rough when I’ve been having the air conditioning on while on Park. It always revs up but not as loud or rough as it does now. Has anyone have this happened.
Since the hybrid AC will run off the HVB for potentially awhile with no ICE, before the ICE has to turn on to recharge the HVB - no there is no difference for me 1 year later.
Same RPM on the ICE when it needs to run.
Did you notice in the winter, on startup when ICE was ran cold for heat - was there some roughness to the idle for awhile in Park?
