I just did a 2000 B16A2 swap into my 99 Si I put stage 3 clutch and lightweight flywheel and performace cam gears... and it has stock B16 Header and my old Cat witch came from 99 Si... So after that I get a engine light on the error is the same each time it said Too Rich Fuel ( Bank 1 ) ... dose any one known how to fix this... do i need a new cat or header or both... i do have a Full back Cat on the car... help..
 
Oxygen Sensor my man! Have someone test it, it should be at 2 volts on idle up to 4.6 at wide open. Have someone test it. The computer knows how much fuel to throw in by the readings from the oxygen sensor. Wrong reading, computer is gonna dump fuel to try and correct a lean condition
 
I put a new Oxygen Sensor in the car an still did the same....could it be my values need adjusting... I putted to the computer and it was tested fine... on idle..

Did you have to do any of your own wiring on the O2 sensor? If so make sure its correct, and if you can test the voltage output of the Sensor at wide open and 2500 RPM

Looks good. with the O2 Sensor but i still get the engine light for the same error and this is what i did since to try to fix it... I got the values adjusted and replaced the fuel pressare Regaulator and also check the Ingentor for leaks and still the engine light came back on.....
