[QUOTE="Denver_FJR, post: 1176820, member: 19217"] I don't think the O2 sensor is used at idle, or at least below about 1800 RPM. During my troubleshooting I also looked at PAIR operation and on my '07 it was typically open, allowing air into the exhaust, below about 1800 RPM. There's no way a narrow band O2 sensor can compensate for unmetered air in the exhaust so the system must be running open loop at least until the PAIR system is closed off by the ECU. [/QUOTE]
