code 43

[alb_accord]

ok so my on line manual doesn't have code 43. it stops at 41. where can i get a more acurate info on this subject?

second after searcing i learned that code 43 is "fuel delivery system" wtf is that. how can i go on on searching/diagnostin the problem.

i also learned from searching that a lot of people are suggesting a bad O2 sensor. but i don't get a code 41 as i should. but at the same time my car didn't pass the emition system saying that O2test came by 150 more or something. i don't have the paper on me.

so what is saying is that it is burning rich. how the F didn't the code 41 didn't come up? if indeed is a bad O2 sensor.

what are the steps that i need to take in order to diagnose this problem

symtoms.
after driving in expressway for about 5 min the check engine light will come up
(code 43). then i will turn it oof.

the muffler tip in the back is all black which migh suggest that is buring rich.

help me out. i need suggestions.

if its burning rich u should smell it... smmmm... awww fresh cranked gasoline! but here in arkansas we dont have emissions test so my suggestion 2 u would b to go ahead n change out dat o2 sensor. especially if it has never been changed... things do age. so get dat check out IMO

which woulda probably explain my code 43... clever bastards... hmm... wnt be gettin it 4 a while tho.

[alb_accord]

i do smell it and the guy that was doing the emition said the same thing. it smelled very bad.

the O2 was changed but i bought the bosch one from auto zone. most of the people here say that those things don't last very long.
i just don't want to spend $140 for a new O2 sensor from the dealer just to come out that it wasn't it.

Has your car been idling badly at all lately? I had that code and symptoms were a little bit of bogging especially at lower rpm's, changed almost my whole fuel system (pump, filter, tank) and the code now randomly still goes on. It doesnt seem to be running rich and the bogging has gone, its a pain in the ass code that is hard to diagnose

[alb_accord]

yeah i have that after the code comes. while stop the rpms will be very low. low to the point that a couple of times i thought the engine will turn off on me.
shit no one knows wtf is up with this shity ass code 43.
