hey tuners I have an 2006 fd1 civic with r18 engine just over 2 yrs. now and its working perfectly but intermittently the check engine light comes on with the code p0172 system too rich bank 1.
I have done a complete service (injectors, throttle body etc.) and also replaced the air fuel ratio sensor with a genuine one and problem still persists. What iv realized is the light illuminates when car is idling with ac running.
I have put the car up for sale but really would like to get this rectified before a sale is made. I am not seeing or feeling a difference in performance or fuel consumption when light is illuminated.
Any help or advice would be greatly appreciated. 734 2853 Joel. Thanks!
