Q: High rpm on parking gear.

asked by on March 19, 2018

The rpm-s go up when the truck in in parking gear, sometimes upwards of 1500rpm, while still parked and idling. It will only go down if the car is taken off parking into to any other gear. Rough and high idle. Accelerates too fast and too easy. What is happening?

Thank you for answering this.
