Just returned from Lexus dealer with complaint of "clicking-Popping" upon de-accerating, braking around 25-35 speed. They test drove the vehicle and determined it normal. I took a test drive with another RX330 recognizing a similiar (but not as pronounced as my condition). The service team described the "butterfly in the carburator " .. when it was closing at a slower speed the condition occurred. I can't buy this. Why some RX 330's and not all? Is this a chronic problem, waiting for a Lexus workaround? Any body else with similar problems. Vehicle has 7800 Miles
