Hey guys, so I read through this thread, I have a 2000 Honda Civic LX 4dr, and my check engine light had came on about 2 weeks ago and my brother reset the battery (neg) and it turned off and didn't come back on until last night again. Figured I should take it in since I don't personally know any mechanics, and they ran the codes and told me my 02 sensor is bad and I should have it replaced because it can mess with my catalyct converter and it will, if not already, giving me bad gas mileage (which it is....).......they quoted me at $100 for parts, and $90 for labor.....does that sound about right? I just don't want to be jipped just because I'm a girl......oh and as a side note is there anyone in the TOrrance, Redondo Beach, Hermosa Beach, CArson, etc are of the SOuth Bay in CA that would be willing to help a poor college student out with any future problems (i.e. checking out my car and/or advising me)
