99 Accord EX, System Adaptive fuel too lean/rich
I have a 1999 Accord EX, 2.3L, 5spd manual. My check engine light has recently come on and the car is idling very low (200 - 400 RPM). By jumping out pins 8 and 13 on the DLC, I found that the code set is for "System Adaptive fuel too lean" or "System Adaptive fuel too rich". It does not specify which.
I have checked the primary O2 sensor and it seems to be generating the required 0.1 - 0.9 volts as well as 17 ohms on the heater.
Can anyone tell me what might be causing this problem?
Thanks in advance for any help!
