It is registering the following FAULT codes on a OBD Diagnostic Computer: P2237 - P0300 - P0301 - P0303 - P0305 - P1632. When starting the engine the "check power-train" warning light comes up on dash and the car runs very very rough and blows a lot of white smoke. there is also a strong smell of un-burnt fuel and exhaust gases inside the car itself and i noticed a clear liquid dripping out of the exhaust which smells very much like fuel. The fuel economy has been terrible for quite some time now.

I forgot to mention the first code of P2271 in my post. Below are the descriptions that the diagnosis computer is showing for the faults:

P2271 = O2 Senser 2 Stuck Rich Bank 1
P2237 = O2 Senser 1 Pumping Current Control Circuit Bank 1
P0300 = Random/Multiple Cylinder Misfire Detected
P0301 = Cylinder 1 Misfire Detected
P0303 = Cylinder 3 Misfire Detected
P0305 = Cylinder 5 Misfire Detected
P1632 = Immobiliser Transponder Response Distorted
