Glen / Duke,

Well I can say for sure the car was warmed up completely considering it was running the entire time the guy questioned the ASR issue but it was idling with AC off so no load really.

The values were:

- Idle RPM Before: 664
- Idle RPM Now: 643

- %CO2 Before: 15.2
- %CO2 Now: 15.1
- %CO2 Limit: not given

- %O2 Before: 0
- %02 After: .2
- %02 Limit: not given

- HC Before: 5
- HC After: 73
- HC Limit: 120

- %CO Before: 0
- %CO After: .01
- %CO Limit: 1.0

******************************************
- 2590RPM Before
- 2519RPM Now

- %CO2 Before: 15.1
- %CO2 Now: 15.1
- %CO2 Limit not given

- %O2 Before: 0
- %02 After: .1
- %02 Limit: Not given

- HC Before: 7
- HC After: 19
- HC Limit: 140

- %CO Before: 0
- %CO After: .04
- %CO Limit: 1.0

The higher RPM's didn't change too much but as you can see the idle looks significantly worse. Note that none of these values are even 30% of the limits except for the HC's at idle which is about 55% of the limit. Do you still think it's an O2 Sensor going south?
