I have a 2012 frontier pro 4x with about 105,000 miles. It doesn’t happen every time but sometimes when I’m parked with the engine running the rpms will drop and the truck will turn off, sometimes it’s drops, almost turns off and the goes back up again. Other times will driving, the truck gives me a quick jolt or a kick it feels like and my rpms jump up and then back to normal. Battery is good not great, alternator was checked good. Any other ideas? I’m hoping the computer isn’t messed up.
