im running a b18c in my ek hatch, motor is stock along with the stock fuel system from the car. the problem is the motor is running really rich. i only got 100 miles on half a tank of gas. the ecu is throwing a code 45 but i dont know how to remedy the problem. any suggestions?

 

02 senor, and 100 miles to half tank isnt bad if u beat it like amofo.

o2 Sensor &gt; Gas Mileage

 

primary and secondary o2 sensors are brand new. and no cel for a bad o2

 

Clean ur o2 sensor and put them back in...If that dont work get new ones!
