o2 sensor problem !!!
so when i drive my car around with it not hooked up obviously it throws a code for the sensor. so i hook it up manually by just hooking a wire from the sensor directly to the ecu. but then it throws a code for Fuel Supply System. so is there really something wrong with the fuel supply, or is it just reading wierd becouse of how i got it hooked up. like does there need to be a resistor in there or something

Re: o2 sensor problem !!!
well, you're still leaving out a lot of details. But what i'm thinking is if you've got the thing running pig rich my some other means, and the O2 sensor is sensing the rich mixture when you have it hooked up, and the ecu is trying to pull a ---- ton of fuel, and it' seeing nothing happen. So it sets a code for the fuel system since it can't change the fuel trim. I highly doubt that anyhting is legitimately wrong though.
