I got a 2016 ram 2500 used to lope at idle on start up for thirty seconds to a minute and then smooth out. Changed filters and clean maf and map sensors with no change. The intake air diverter valve went out so I deleted the truck still didn't change but now it is beginning to get more frequent and lasting longer. And now will sometimes do it while idling after driving. Any suggestions would be appreciated. Truck has 76000 miles. Has egr delete kit and replaced the intake horn with the banks monster ram 3.5in when I did the deletes
