2008 Honda Accord

I am selling my 2008 honda accord. I did not want to sell it since it is a gas saver. I would drive this car to work every day. Just last week it started giving me problems. My husband and I thought it was catalytic converter so we replaced it Brand New. After replacing it the car gave us another code saying it was 2 sensors. We bought 2 brand new sensors to replace them. After replacing them it still gave us the same code. We are thinking it is something electrical. It could a cut wire. The reason i am getting rid of the car is that I have already put a lot of money into the car and I no longer want to spend more money. Car is tagged till October Car turns on and runs. Brand New catalytic converter The four tires are Brand New Preferably looking to sell the whole car but if looking for engine, transmission, catalytic converter. Engine - $900 Transmission - $750 Catalytic converter - $450 $2,150 OBO
