1999 Ford Windstar 6 cyl Front Wheel Drive Automatic 75k+ miles 3.8L V6

Is this amass air sensor code?
I can't find a photo that looks like my car's set up.
Is the MAF the part between the throttle body and
the intake manifold?
What do I use to clean it, throttle body cleaner,
contact cleaner, or must it be the CRC MAF cleaner?

DTC P1131 indicates the system is correcting RICH for an overly LEAN condition. The Heated Oxygen Sensor (HO2S) voltage is less than 0.45 volts. This is usually due to a vacuum leak after the MAF. It can also be caused by a bad PCV valve or PCV system hose

Thanks, guy at the parts store told me that the 1131 code was air mass, and P0135 was #1 bank O2 sensor.
