Question about 2000 Pontiac Bonneville
Ok someone help me i have four fail codes that come up in my car and i have no clue what they are, P0201,P0203,P0205,P0300, i really need to kow what is wrong with my car and how much it is going to cost to fix it.
Ok the codes po300 is telling you that you have a misfire on diferent cilinders, and the 201, 203, and 205 is telling you then the fuel injector number 1,3,and 5 have a problem, if you know where the injectors are, you can buy a little knoid light to see if the computer is pulsing the injectors with the car runing, but most likelly you are going to need to replace all the injectors, because when one goes bad it is recomended to replace all of them, they are between 35 to 95 dls each, but b4 repalcing any parts, make sure to have it chek to make sure if the injectors, or the circuits feeding the injectors is the problem. good luck and i will apreciate the ranking. and the misfire is caused by bad or inoperative injectors, bad spark plugs, or plug wires. but in this case seems to be injector problem.
