ECU Light On
I just swapped out my OE Water Pump and Tstat this weekend for the RE-Emedy parts. My ECU light it on. The car ran fine on a test drive. It ran rich, 13 AFR (I have a W02 gauge).

Gauges work and it idles fine. Cobb cant work because it can't comm with the ECU.

Any thoughts of why my ECU light is on or any troubleshooting steps?
