ok so i figured the only thing wrong with my car was a bad upstream o2 sensor, turns out i may have been wrong now... when i read the codes on my car i got 3 diff ones p0135 - which is the o2 sensor, p0301 - which is cylinder 1 misfire, and p0403 which has somethin to do with gas recirculation circuit or something...

ok so now im not to sure on what i should do, before i took my car to the mechniac that rebuilt the top end of my motor i never had these codes pop up, he had replaced my spark plugs and everything and even told me i needed a new cat, so now im not sure if he hooked everything up right or not...
