| Description of the problem | At vehicle start- cold ambient temps -approx 20f and lower, engine goes to about 1800 rpm and stays there for about 2 minutes before dropping down to about 1100 rpm. After shfiting and the driver taking the foot off the brake pedal the vehicle has a tendence to lurch due to the high engine speed. This is a surprise event every time i or my wife start this vehicle and i consider it a safety related issue. As a comparison, my 2003 chevy trailblazer cold engine rpm never goes above 900 rpm and does not exhibit this lurch tendency. I complained to the toyota dealer service manager, and he offered no resolution- basically "... That's the way it is." the dealer has no known procedure to adjust the cold start engine speed to a lower level. I have a documented service report. |
