I just replaced the right side O2 sensors and after driving approx. 75 miles the check enginne light has come on. I checked the front sensor connection (the suspect). Any ideas on what might be related to O2 sensors and CEL?
I don't have a code reader. I've disconnected the battery and the light went out, but then came back on again. I'll probably need to find someone with a code reader. Right?
yes you need a code reader if not your shooting blind and you will replace all your emissions before your done, you can buy cheap versions for about $100 with the ability to erase the codes, and if you are near an auto zone store they do it for free,even if you buy one it will be less than an O2 sensor.....
