Hey guys. I'm currently experiencing a weird engine rev. When I pull up to a stop sign and come to a stop, about one in ten times, the engine will rev to ~1500-2000 RPM. No matter how long I wait, it will not slow down on its own. The only way to make it stop is to let off the break and let it drive. Generally, after about a hundred yards or so, it will straighten out and go back down to idle, at which time I can drive on without a problem. It doesn't seem to have any correlation about how quickly I stopped, the speed I was going before I stopped, or how hard or soft I press on the break.
Any idea what could cause this? I've been looking for relevant posts all afternoon and haven't found any.
Also, I'm not sure if it's related, but when I start the truck, it surges to 1500-2000 RPM for about a second, then goes down to normal idle. I still have no idea what is causing this. I've checked for air (put a clear hose coming off the IP return; no bubbles) and run copious amounts of injector cleaner, but still no change. The issue with the breaks is new, the surging has happened since I got the truck.
I really don't want to have to resort to putting it in the diesel shop, but that may be what I end up having to do.
Thanks,
Christian
