You need to get it scanned first , It could be a number of different things including 1. Engine Coolant Temperature Sensor 2. Lambda Sensor ( there are 2 Bank 1 is the one closest to engine Bank 2 is the one furtherest away from engine ) 3.MAP sensor ( Manifold Absolute Pressure ) located near to the dipstic tube at the rear and on the side of the engine , as i said you need to get it scanned.
