please help with your knowledge
i have a 383 motor in my 93 vette and had pcmforless burn me a chip. From day one the car ran extremely rich so i datalogged it. It revealed a bad o2 sensor, so i changed both sensors. I datalogged it again and the tech tells me the o2 sensor is still bad. What is going on? I just want to hear what advice anyone has about handling this situation. Would fouled plugs fit the suspect? or is it possible the o2 sensor was junk from the store? idk, but some help would be nice because i am going nuts. thanks
