P2188 System too rich at Idle Bank 1

Neglected to mention, car has 120,000 mi. (190,000 km).

Too much fuel injection (flooding) suggests the MAF sensor signaling more airflow than there actually is.
I decided to clean the MAF sensor, using a MAF Sensor cleaner spray.

This has smoothed out the idle, although it's a bit high (850 RPM) in neutral.
