you will get all info and solutions there definitely

Needs to go to a repair shop, to be road tested with scan tool,
& the codes properly diagnosed,component tested & the vehicle
repaired as required

You can Google your codes

Type: OBD & the code

OBD PO300

Google the code

Type: Mazda OBD P2195

Read up on the problem

You obviously know nothing about todays
technology or codes

If had of Googled the code, you would see
it has to do with an Oxygen Sensor

Google: OBD P2195 Ford Codes

Vehicles have no way to know what fuel your putting in them

The combination of the 4 codes leads to low fuel pressure, bad injectors or a leak in the air intake.

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.

02 sensor is stuck lean ( bank 1 sensor 1 )--bank 1 is the side for # 1 cylinder. oxygen sensors usually wear out at between 80.000 and 100.000 miles. sensor 1 refers to front of convertor. p2195,

let me know if this help you....

Generally The brake light only indicates the parking brake is on and/or low fluid in level. You are correct that it indicates a vacuum leak recheck ALL vacuum lines you should be able to hear it as well.
