Hello, I had my check engine lite come on my 1998 KIA SPORTAGE 4 cylinder, automatic trani, 2.0 liter engine.
THE AUTO STORE said it was a BAD DOWNSTREAM O2 SENSOR with error code of PO137.
I replaced the sensor and the same code is coming up. Any help MUCH appreciated. It just had a tuneup. The sensor was brand new that the mechanic installed. STANDARD MOTOR.
Please email asap
have the same problem?
