I have a 1999 Chevy Malibu. The check engine light has been on for about 6 months now. The original code was for the o2 sensor in front of the cat converter. I changed the o2 sensor and the light went out for about 2 weeks. Then it came back. The same code came up again. I then took my car to my regular mechanic who said that the code could be many things. He messed around with some wires with the map sensor and once again the light went away for a little bit, but it came back again. I am getting frustrated and if you have any idea what the problem could be please help me!
Thanks!
