that is the system that supplies the fuel to your car. are you having problems with it other than the CEL? or does it seem to be running fine?

the more details the easier it is for people to help you.

 

Fuel Supply or o2 Sensor.

I had code 43 on my Accord, turns out i needed an o2 sensor.

It would only come up after i drove the car for a while.

more details : never had check engine light ON when first turn on car, only after i drive it around when its COLD (not fully warmed up) and then it turns on, and i turn off my car, turn it back on, and its gone. so code 43 most likely means my o2 sensor going bad??

so right now its thorwing this CEL 43, but no check engine light, will it affect anything with performance as of right now ??

 

It will affect your gas milage alot.
It can also damage your Cat.
Those are expensive to replace.
Im sure there are more things you can damage by running too rich.

Go to Autozone and get a Bosh o2 sensor for $55.

even if i have no check engine light?? wow how much performance r we talkin about??

 

from the set-up i saw on your cardomain site for it being a mild set-up i dont see you losing a whole lot of power but get that sensor installed re-set the ecu and with gas prices the way they are it will pay for itself quickly. oh ya BTW mad props on the rear lip (i have the same one) GL with the prob.
