[Shotimes] Codes 176 & 214

[Ian Fisher]

Mike
I suppose yout theory holds some water but I don't
really know the answer. However, your description of
the light coming on after spirited driving is the
classic symptom of an O2 sensor issue (in my
experiences) as the code indicates. How old are the
O2's? Does your car burn any oil from ring wear?

Out of curiousity, which MAF are you running?

I'd replace the O2's and forget about it. Hopefully
the light will not come back on. You could always try
testing it with the LPM out and stock MAF back in to
see what happens. Good luck-replacing the O2's on an
atx is a barrel of fun. :)
