Engine Lunges forward sometimes

This could really be a bad thing if my foot was not on the brake at the time. While sitting at a stop light, the engine lunged forward like I had my foot on the gas pedal. I also experienced a long time ago in my garage about 3 feet from the wall. I was so glad my foot was on the brake pedal at the time.

Any ideas about what is causing this. It is so irregular that I dare not take it to a garage yet. 324,000 miles and runs great otherwise. Happy with this vehicle since buying it new with 8 miles on it.

Here's a thread from someone else with a similar issue. Replaced the throttle body. See below.
