2009 Toyota Venza Wagon 4dr Wagon (2.7L 4cyl 6A)
Throttle Suddenly Maximizes at Times
 We love everything about our Venza except for one MAJOR problem. Twice now the engine has suddenly surged very SEVERELY and LOUD for about 10 seconds or so. It sounds like it goes from a normal idle to a sudden maxed out, floor-boarded throttle! We had around 3000 mi on it the first time this happened, and then this last time 9200 miles. It's been in park both times its happened, but we're afraid its gonna happen while driving.  Toyota checked it over thouroughly and couldn't find anything wrong. The car is perfect outside of this problem. Like I said, we love it, but we sure do regret buying it.
