Hello, I would like to get some help before wasting more money. The "check engine soon" light came on and it gave 7 codes 5 pertaining to 02 sensors and 1 for the catalyc converter and 1 for the EGR...I swapped the 2 02 sensors in the car and now I am down to 3 codes but they are P0133 P0141 AND P0136 which they all pertain to the 02 sensors and the 02 heater circuit malfuntion. I check the fuses and yes the fuse on the engine compartment was blown and I replaced it. I went to Autozone again and once again the 3 codes came up the same one' now I am so confused what should I do and what do you think is wrong?? Please help and I am up to $150.00 is just two sensors......

Thanks for replying to my question, but were exactly on the engine they are located in..Please use relative location ex: before the catalyc converter or close to the water pump etc....I am sorry I am naive when it comes to automotive terms....

Yes you were right they are located in each manifold. In case someone has a question like mine on same car If they click on the link they will find them very quickly. I found mine..Also do you know what the one in the back of the engine is called? I called Autozone and they claim that I am wrong the car only has 2 O2 sensors. I know it has 4 because I saw them and touched them with my hands....Thanks Chevy II you are the greatest...and also thanks 2car pros...I will make a donation..This is the best website and yes I will help you guys keep this one open for all of us out there that need your help...
