Did some shopping and found it cheapest (129.00) at Partstrain.com.

Good call. Sometimes that is the smartest way to go.

OK... Here are the results of my failed emissions test:

RPM 2500 - HC PPM 203 (Limit 220) PASS / CO 1.33 (Limit 1.20) FAIL
CO2 14.0%, O2 1.5%

RPM Idle (778) - HC PPM 541 (Limit 220) FAIL / CO 2.54 (Limit 1.20) FAIL
CO2 14.4, O2 1.8

So apparently 2500 RPM is close to passing and idle is terribly out of limits.. Gut tells me that it's got to be the O2 sensor right? seems like its very rich at Idle..

Should have the part next week.

What's that? Buying the expensive OEM?

does seem rich to me. likely it is the O2 sensor. i suppose it could also be the temp sensor.

Check your tps adjustment as well if it is not adjusted right it will overide the idle map.

Splice in a Bosch 13913 O2 sensor! Remember to crimp the connection, no solder.
Rough running you may want to unplug the sensor to see if the car runs better .. if it does then it is the O2 sensor... if it doesn't you have other problems you should make sure you do a tune up if you have not already done so and check for air and vacumn leaks.
