bad 02 right ?

[dsm4life]

I did a run with my logger and the volts on the 02 didnt pass .3 . Also my a/f guage reads lean all the time and i have a 190 rewire with stock injectors which should make me run rich right ?

yes, bad o2. you might want to clean it first with brake cleaner before going out and buying a new one, i was having the same problem and it worked on me. just pull it out, spray it, let it dry for a few minutes and put it back in. if that doesn't work then yeah, buy a new one.

If you dont want to get ripped off by the dealer for a o2 sensor since they are like $120-140, just go to pepboys and get a generic one and wire it up yourself. They work just as good and only cost about $50. just my 0.02 cents
