My question. This vehicle is a lineman bucket truck that probably has more time idling that actual road miles. Is it possible that extended idling can cause drivability issues? Sometimes after idling for several hours or more and when leaving the jobsite, the truck seems it has a loss of power at times. It is sporadic at times.
Thanks.
