The code P0102 in most cases isnt a bad MAF sensor. It is in most cases the connection to the power source or loss of power to it. It means that the sensor is not getting enough voltage to start with. in the cpu is a voltage regulator that drops 12 volts to a 5 volt range. i think that you either have a poor connection at the sensor or lading to it, or the regulator it the cpu is failing.

Please do accept the solution and revert for further assistance.

Coolant on the spark plugs is a classic indication of a failed cylinder head gasket. No point in doing any further analysis 'till you get that squared away. When you replace the head gaskets, it's always advisable to have the heads checked for cracks and warpage.

Let go with your theory

You get a PO102 MAF code.( Mass Air Flow Sensor)
Lets say the sensor is somehow not working correctly,and as you say,it has spark and fuel

I would guess, you think, the engine would be happy, having no idea how much air it is getting. Kind off like the computer will somehow overlook it is controlling an air pump in the first place.

I have a1997 grand pri the gas mileage dropped from 28mpg to 16. throws code p0102? any ideas?

PO102 indicates a problem with the Mass Air Flow Sensor. Aftermarket air filters that require frequent oil to be applied to them can coat the sensor wire.
The most common issue, or starting point is to inspect the air induction tube for any leaks between the sensor and engine throttle body. You failed to mention what engine.
Cleaning the mass air flow sensor wire may be all you need. Good luck

I have a problem with my 2001 Toyota sienna, took it to inspection yesterday to get inspected and didn't pass results Cat not ready and evap not ready, inspector tell us run the car couple miles and bring...

If the "evap not ready" readiness monitor never clears and you keep getting P0440,P0441,P0446 type codes, then you have a problem with the evap system. You have already tried the gas cap (good start) but there are about 6 other things it can be from electrical VSV air valves (there are 3 of them, 2 under the hood, 1 near the charcoal cannister (behind fuel tank) to 2 air operated valves on the front of the same cannister. There is also an air line that goes to one of the electric VSV valves on the air cleaner under the hood. Several oil change places have been guilty of pullling these off and not reconnecting them.
