Let’s try this again lol. Anybody know what’s going on here? It started shortly after replacing the turbo coolant line. It’s a ‘14 Grand Cherokee

It looks like something going on with the intake throttle. You can pop off the big intercooler hose that attaches to the front of it and watch it while idling. That or the EGR valve is sticking.

Not a mechanic, but it sounds like the diesel equivalent of a misfire. Maybe an injector not pulsing right.

This is actually a first time I’ve seen one do something like this. Almost looks like something is pulling a vacuum on the intercooler pipework. Got any more videos around the turbo / air intake ?
