alright,
i just finished a 1g b16 in a 92 ls, I installed a S-afc while i was at it. I decided to do the blue wire mod to be able to tune it a bit better than this dumbass autometer a/f gauge. Anyways i start the car and the o2 sensor voltage slowly starts rising and then peaks out at about .7v and then starts slowly declining agian. during this time i get a CEL, its code 43. I assume it the o2 sensor cuz the voltage is screwed up. Butthe car runs fine, no missing, or idle problems, so i know its not the fuel supply. The A/f gauge reads the same thing as the sensor check on the s-afc with the blue wire mod, i have doule checked that both the gauge and s-afc are both hooked up correctly as well as connections on the o2 sensor, and the gauge.
I am getting very irratated with this and spent 2 hours searching and found no help.

anyone have any suggestions?

Code 43 Fuel Supply System defective or malfunctioning fuel supply system


I was kicking the same code whenever I had my SAFC increasing more than 8%
I was informed the correct way to tune the SAFC is to INCREASE Fuel pressure and -x%

 

the afc is set to stock, I haven't even messed with the fuel trims yet i don't have anything to tune it by. I am positive its not the fuel system, the car runs fine. Its got fuel pressure and the i used all the parts from the old motor, like injectors, regulator, and all that ****.
Im sure its the o2 sensor cuz it dont work.
any other suggestions on what to try to get the o2 sensor working?

 

Ok well code 43 is Fuel Supply malfunction....

i dunno .. good luck ... hopefully someone else might be able to chime in with experience reguarding the AFC wire 02 fuel/ratio trick
