I have a '03 Lancer ES. I had my engine light on and had it checked. I was told it was my O2 sensor so I got a second opinion to be sure and was told the same. I ordered the sensor and my brother in law installed it on my car before i could even open the package to make sure it was the right one. So i had a mechanic check and clear the engine coding. About 3 hours later the light came back on. On my invoice from the mecahnic, he listed the codes. whcich are PO135, loosely tranlates to O2 heater Bank 1 sensor 1; the other code PO421, warm up cat efficiantcy low. I just when to Auto zone for them to run a diaignostic and the code for the 'cat?' came up. Please someone tell me what these are specifcally pertaining to. Also, prior to the engine light initially coming on, there was a recall on the catalytic converter..so that was replaced...the light coming on shortly after that? What's going on with my car? I don't wanna shell out more money but my little girls ride in it.
