93 Octane

3 logs from driving around today.

15_12_21 - stop to normal driving for ~30 seconds 15_14_41 - 15_19_42 -

Noticed the Lambda 1 AFR would turn rich (12-13 AFR) for 1-3 seconds after releasing the throttle at 60mph. Would this possibly indicate a leaking Injector? Shown at towards the end of the log where Pedal Input shows 0. Also had a rough Idle, both in Neutral and Drive @0mph. The fluctuations seemed to coorelate with slight spikes in AFR [15-16.00]
