Having problems with your Mitsubishi Galant ?

The service engine soon light is on. I had it diagnosed and the codes were PO136 (sensor 1, bank 2) and PO141 and PO304B

Ok, po136 is the O2 Sensor, P0141 is is the same problem and the P304 code is most likely a faulty spark plug or maybe a wire. Go to one of the Major auto parts stores and get an O2 sensor and the socket to put replace it with cost about $50 for both and replace them. After you replace the O2 sensor disconnect the negative battery terminal for 1 minute to reset the computer. Remove and clean the #4 spark plug and make sure it isn't fouled, if it is replace all the plugs. It may be a good idea to do so anyway, when the O2 Sensor malfunctions you usually end up running rich and that fouls the plugs pretty badly.
