Nope, but I did start a new thread. My problem went away for a long time, and just came back. I'm going to replace the throttle body and the accelerator pedal. The only unknown (for me anyway) is that I've read that if either of these components get replaced, then a trip to the dealer is in order, so the engine can "learn" the new components.

 

Owl - I’m running into this exact same issue. It started a week ago and has gotten progressively worse, happening multiple times in a single drive. Almost always happens at low speeds and restarting the engine clears the issue, but not for long enough!

Any more info on this resolution would be helpful. I’m looking for a mechanic in the Philadelphia area to take it to.
