sound like my set-up. O2 sensor should be ok if your CEL hasn't came on yet.

 

I really don't think its bad but IF you really want to check it, then you will need a pretty good scanner. Some of the OTC scanners have the ability to read your O2 by bar graph. (Mac tools also offers one). With one person driving and the other holding the scanner, you will get to see what it is recieving and what it is thinking. No matter what rpm, it should look in a pattern form, repeating itself over and over. You also really need someone who knows what the readings should look like.

 

i just bought a new ngk for like 80 bucks so il just replace it o well
