Gathered some data while idling in my driveway. With ignition in on position and car not running, all o2 sensors read a steady .4v
Once up to temp idling, both primary sensors oscillate between .1v & .7/.8v
Post cat o2 sensors read as follows:
bank 1: Steady .7v
bank 2: Bounces between .4v - .5v
Fuel trims maintain between (-)1.5% - 2%
Any ideas on interpreting this data?
I do have a very slight exhaust leak at the header/resonator interface btw
