[xyzse]

i took my car to my honda shop and he said i had a check code saying fuel supply? he said it could be two or three things, clean fuel fuel injectors or fuel pump and other things. i dont want to pay money for extra stuff if thats not the problem.ive already changed the fuel filter,pcv valve, bought new egr valve- he also put a plate in it.it seems like im loosing a lot gas mileage because of my problem.or do i need to clean valves and throttle body of black carbon build up.i have 190k miles on it.any ideas?thanks

if it was a code 41 or 43, it's a o2 sensor issue. It would also explain your crappy gas mileage,

its simple, either its in your down pipe, right before your cat you unplug it and screw it out, probably need either a o2 sensor wrench or a adjustable wrench(and for the life of me i cant think of what its called -_-) and screw the other one in(put anti-seize on it, should come with the o2 sensor) and plug it in, reset ecu also, just take ground off battery and the back-up radio fuse out before you start and put back after you change

You'll need to get one of these to remove it easily:

I don't know about the rest of you, but my O2 sensors were ALWAYS bitches to get out! It'll help to start the car up and let the header/downpipe warm up, wherever your O2 sensor is located. Penetrating lube may make your job easier as well.

Yeah, warmth and a good overnight soaking in PB Blaster will be a great help. Especially if that sensor has been in there for 20+ years.
