Check Engine Light/O2 Sensor replacment
My friend just recently replaced his lower o2 sensor and he reset the ecu according to the thread on here. His check engine light is still on and blinks on startup. It also has a rough idle and seems like it wants to die sometimes at stops. Is there anyone who has any input on this issue? thanks!
