O2 Sensor
I bought one of the Walker O2 sensors on ebay. After 425 miles I received an error code p1164 (Primary HO2S (No. 1) Circuit Range/Performance).
What does this mean? Bad sensor? Should I get a genuine L1H1?
Would it matter that I have a header on and am running the O2 sensor just behind the engine versus that standard location with an oem exhaust manifold?
