Let's say in a 30-minute drive, I'll feel it once or twice. It's so mild that I could be confusing it with the crappy NJ road conditions to be honest.

At the moment, I have an appt with a well-known indy shop next week so if this doesn't resolve, I'm just gonna bite the bullet and take it in.

I'll keep this thread updated.
Can you calibrate the transfer case to rule it out. You won't need fresh fluid to just Calibrate/ test it. You can do it through ista+. Also if it does end up being injectors don't drive until you fix it. Fuel will wash oil out of cylinder and cause scoring.
