code 43
yeah so i'm on my way to work yesterday and i'm just crusing and all of a sudden i decided to get on it a lil bit and i just stomp on the gas didnt down shift. and it feels like i doing nothing...it sounds like the engine wants to rev high but it doesnt. then after this happened a couple times the engine light came on and i check it out and its code 43 which is fuel system. my question is where do i check and has anyone else had this problem?
oh yeah its a 94 ls (stock motor)

Re: code 43
I have a diagnostic chart for code 43, if you got a fax # I can send it on over. It gives you a step by step procedure to check code 43.
The description given is
Code 43: A problem in the heater oxygen sensor (HO2S) circuit, or a problem in the fuel supply system.
Let me know.

Re: code 43
A faulty heated O2 sensor will give you that code.
After I did my (B18C1) swap into my Civic hatchback, I got the same CEL code of 43. I changed out my oxygen sensor and the code went away.
