I was wondering if unplugging an 02 sensor was an accurate way of testing to see if they are working properly?
Thanks,

No i don't think so. That will do nothing for you really. The proper way is with a data log, i think it has to with the voltage, and the BLM's or something like that. I have read some posts that people were looking at someones log and said that the BLM's on it were so far apart, and one was too low or high and it meant that the O2 in that side was not working properly.

 

I would not consider it an accurate test by any means.

 

I have an AutoTap scanner than I can use later this evening when I get my cord.What things do I need to list so I can get some help?My car acts up a little when it gets hot but at wide open throttle it's flawless.I thought I read a post saying "if you unplugg the 02 sensor and the problem goes away it's probably the 02".Maybe I read wrong though.

Unplugging stuff for troubleshooting is bad science, IMO. Record a data log, so that others can look at it and try to see what is going on. A snapshot won't really help.

 

Just to update this thread,I hooked my AutoTap scanner up and noticed the Bank 1 02 was not fluctuating like bank 2.It would'nt even fluctuate over 30mv's.New 02 sensor fixed my problem.

yeah i was gonna say a lot of times a bad o2 will not fluctuate as much as it should. congrats on a problem easily fixed
