The firing order is 1-4-2-5-3-6. The cylinders are, front bank is from drivers side to passenger, 6-5-4 , and 3-2-1 at the firewall.

P2195 and P2197 means that the O2 sensors on each bank are seeing WAY
too much oxygen in the exhaust gas. In normal operation the signal from
the O2 sensors should swing back and forth between rich and lean...
Your sensors are locked on lean. Replace both O2 sensor.
Hope helps (remember rated this).

The descriptions for your codes are:
P2197 - H02S (RF) signal stuck lean
P2195 - H02S (RF) signal stuck lean
P2187 - Fuel System too lean at idle
P0102 - MAF circuit low input
Essentially what's happening is that your MPV is running too lean when at idle. Too much air and not enough fuel. As you speed up - it forces more air into the system which alleviates the problem.
Examine your mass airflow sensor. It should be completely clean - no fuzzies on it at all. If so - purchase some mass airflow sensor cleaner to clean the sensor. ONLY USE THE PROPER CLEANER TO AVOID DAMAGING THE SENSOR. Disconnect the battery to reset the system and turn off check engine light.
Otherwise you will need a scan tool to look at the voltages being supplied to/from the PCM for each of the Heated Oxygen Sensors and the Mass Airflow Sensor to determine which part is creating the problem.

My car did that once and I didn't have my gas cap on tight. Not the same model but worth trying.

SOURCE: I have a 2005 Mazda MPV with 83,000 miles and the engine light came on with codes P2187, P2189, P2195, and P2197. I was told all four O2 sensors need to be replaced. I put some Sea Foam in the gas t
The combination of the 4 codes leads to low fuel pressure, bad injectors or a leak in the air intake.
