I ride a 91 firebird with the 3.1 V6 engine. Last ride the Check Engine light went on, I flashed the code and it was 41 wich indicates a malfunctioning krank position sensor. But from what i heard, the engine shouldn't start anymore after shutting down, mine keeps starting and driving with no particular hassle. Can anyone please post a picture of where the krank position sensor is located on this 3.1V6 engine, and has anyone an idee how to check the "mal"function of this sensor, or an idee of what could be another reason for the 41 flash code. Thanks from rainy Belgium
