I own a 1st gen vitz 1999 model. The car is so cool but the only problem is that when I'm in a speed (suppose 100kph) and suddenly I want to reduce the speed and I take my foot off the accelerator, it won't reduce the speed instead the engine start making voice as if I pressed the accelerator so hard. As a result I have to use only brake to control my car. But this happens sometimes not all the time. My car is automatic.
