Will a bad o2 hurt ETs?
Will a bad o2 hurt ETs? I was while at the track and still am throwing P1133. Which is the driver bank front o2. Just curious as to if it would hurt my ets? I ran 13.1@110.3 with a 2.18 60' with my street tires and chrome 18s.
Will it help the ETs to replace it before I go back?
TIA

That particular code doesn't necessary tell you that you have a bad 02. It is a common code if you are running headers and that code is set for at idle only, or when you first start your car. If that is the reason you have that code, then no it should not effect your ET at the track. But if you really do have a bad 02, then yes, it would efect the performane of your car. Your fueling could be way off because of a bad 02.

EDIT: also, the code never comes on at idle. Only when driving after its warm. It always lights it up for about a week-2 weeks and then while driving it will just go away for another week at most, then comes back.

This maybe more info than you want, but here it is. lol
CONDITIONS FOR RUNNING THE DTC (P1133)
The HO2S lean to rich and rich to lean switches are less than a calibrated amount.
ACTION TAKEN WHEN THE DTC SETS
We have found that the rear 02s from a Corvette do a better job when you have headers. So if you are going to replace them, those are the ones I would recommend getting.
CONDITIONS FOR RUNNING THE DTC (P1133)
- DTCs P0101, P0102, P0103, P0106, P0107, P0108, P0112, P0113, P0117, P0118, P121, P0122, P0123, P0200, P0300, P0410, P0440, P0442, P0446, P0452, P0453, P1258, P1415, P1416, or P1441 are not set.
- The loop status is Closed.
- The engine run time is more than 160 seconds.
- The engine speed is between 1,000-2,300 RPM.
- The ignition 1 signal is between 9-18 volts.
- The Engine Coolant Temperature (ECT) is more than 50°C (122°F) .
- The Evaporative Emissions (EVAP) purge solenoid is more than 0 percent .
- The Mass Air Flow (MAF) is between 20-50 g/s .
- The Throttle Position (TP) is more than 5 percent .
- The fuel tank level remaining is more than 10 percent .
The HO2S lean to rich and rich to lean switches are less than a calibrated amount.
ACTION TAKEN WHEN THE DTC SETS
- The control module illuminates the Malfunction Indicator Lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
- The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
