I'm seeing oddball A/F activity, and I'm officially blaming my O2 sensor.
First, the weird activity: the gauge is occasionally holding solid at 1V, and it'll stay there for an extended period of time (10-15 minutes). This usually happens whenever I'm driving in-town, and always happens with any kind of track use. Once the car cools down a bit, it starts doing it's usual blinking dance. (I usually just idle for a bit; getting on the highway and holding at a constant RPM for a while seems to do it too.) I've seen no obvious side effects, but my seat-of-the-pants estimation is that I'm hesitating a bit from 5000RPM and up when at WOT. I'm assuming it's the front O2 sensor going bad, although I'd love to hear another diagnosis.
So, following that vein, I've been looking at different O2 sensors. OgygenSensors.com claims that the original part is Bosch P/N 13425, or Chrysler P/N MD313819, and I've found a few places selling them up to $120 (Conicelli). OxygenSensors.com is selling an OEM replacement for $83 (or a universal replacement for $60), made by a company called "Walker". I've also found MachV selling a Denso unit which claims to be resistant to lead poisoning for $121.
My questions are pretty simple:

My questions are pretty simple:
- Is the Denso unit worth the difference in price (ie. does it work as advertised)?
- Has anyone had any experience with either the Denso one MachV is selling, or the Walker brand sensor? Any comparisons you could make to the stock Bosch sensor?
- And, most importantly, anyone have better prices than what I've found above?
(So far, OxygenSensors.com has the lead, being $83 w/free shipping.)
RIGHT AROUND 65$
