Cold Starting Problems
Vehicle would stall if put in gear after staring. the Fuel Filter and Sensors would Vibrate like crazy and like it was going to fall off. But every thing would smooth and quiet if the engine is left for 10 to 15 minutes to idle and it took this much time to reach 30 Percent of the temperature gauge scale. Changed the following parts 1 by 1 . Coils,Plug, Throttle body assembly from scraped vehicle., Idle air control valve but nothing changed. Finally one mechanic kept the vehicle for a week and zeroed on the VVT Sensor and Cam Shaft Position Sensor. When These two were changed all the starting problems got solved.
