If you can reproduce over and over I would take it to the dealer.
Weird idle problem
When at idle but only in park about every minute or so the engine Rpm will drop to almost stall rev back up to above normal then back to normal and then the cycle happens again. Occasionally it will stall. No check engine light. No pending codes. Any help or direction would be appreciated.

My thinking as well. I would also check all of the hose clamps on the air filter box, throttle body, etc. Maybe you just have small vacuum leak or possibly a communication error/glitch between the gas pedal and throttle body.If you can reproduce over and over I would take it to the dealer.
Just another thought, was your AC or defrost on when it was doing this?
