High idle after driving and put in park
Ok so I have a mini max with the dpf present. Seems like sometimes after driving hard or even casual it goes to a high idle once put in park. The break will bring it down; once let off it goes back up. I know some trucks try to cool down by this but mine is not running hot nor is the fan engaged? What could this be? Its hard to tell if its the mini max since I put it on a few weeks after buying the truck. It kind of trys to do it in drive every now in then.
Anyone ever have this issue?
