Mass Airflow sensor is attached to the air breather system usually near the air filter. Its usaully a square box looking thing with a wiring harness on it. Here is a pic of one below, but keep in mind this is not a pic of one from a intrepid

.Engine stalls, won't idle, bucks at 3700rpm


Sounds like mass airflow sensor to me or your timing jumped. Probably high miles too, eh? Could possibly be voltage regulator but I highly doubt it.

My 1991 240DL volvo has a hard start, and while idling, goes up and down, then eventually stalls out. The air flow sensor/air mass meter? was unhooked, and the car idled smoothly. Is it true that the car...


When you unplug the mass airflow sensor, the car goes into "limp home" mode in which it runs full rich. Generally speaking, if a car runs better with the mass airflow sensor unplugged than with it plugged in, the mass airflow sensor has failed.
However, the drifting idle tends to make me want to look for vacuum leaks and check the rear temperature sensor on the driver side of the head. I suspect that running over-rich is compensating for the vacuum leak so the car keeps running.
If you have a propane torch or a can of diesel starting ether, spray it around the intake manifold while the car is idling and see if the engine speeds up. If so, then you have found a vacuum leak.
If it were mine, I would buy a new intake manifold gasket and replace it as a routine maintenance item. It is not expensive or difficult to replace except that if you are like me, you WILL drop at least one nut, and there are several great hiding places on that side of the engine where the nuts go to hide when you drop them. You will need a magnet to recover them. You don't need to pull the manifold clear off, you just have to pull it clear of the bolts so you can slip in a new gasket. You can leave the throttle cables and most of the other connections hooked up
If you know how to use an ohm meter, you might consider getting a manual for this car and looking up the appropriate resistance/temperature values and checking that rear temperature sensor.
While you are replacing that intake manifold gasket, check all the vacuum ports to make sure they are clear, and check all the vacuum hoses to make sure they are intact. Also check the tubes between the mass airflow sensor and the throttle body for cracks. While you have those air tubes off, clean the throttle body and the idle air control valve with some carb cleaner. Spray a little carb cleaner through the mass airflow sensor as well. Actually, there is a special spray for cleaning mass airflow sensors that is more gentle, but I have used carb cleaner on them many times with no apparent ill effects.
If it turns out that the mass airflow sensor has failed, that will run some $$, but having a fresh intake manifold gasket and clean throttle body and no vacuum leaks will be worth your time and money and make the car run better when you are done.

I recently had problems with my 2005 Mazda MPV stalling. I came to this great site and changed the IAC and it stopped stalling. But 2 days later my check engine light came on. The codes are P2197 P2195...


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.

1999 mazda protege when starting of at a slow speed the car starts to buck and o/d light will flash


The tube after the air filter might be cracked (Fix it). Next the you will see the Mass Airflow Sensor. Unplug that and see if you car runs differently (better while driving, worse while idling). If so then it is definitely the MAS (Mass Airflow Sensor). There is actually a recall on this part (at least, for the 2000 Protege). Also, try cleaning it and plugging it back in. Change spark plugs (OEM only, nothing fancy). Also, some gas does this worse than others.

Mass airflow sensor


It's usually mounted between the air filter housing and the throttle plate, in that big round hose.

Vehicle stalls sometimes


could be either the cam sensor or crank sensor , but I would check the crank sensor first , this sensor will not cause a check engine light either

Not very technical at the moment, but I can tell it's in the fuel sensor system, not fuel delivery. Check the Mass Airflow Sensor, and related sensors.

1999 buick lasabre hesitation while driving.


there are really only 2 things that cause this problem most of the time i have seen it, 1st a defective Mass Airflow Sensor, the second is low fuel pressure from a failing pump or obstructed fuel filter do u have a check/service engine soon light on at any time? have u had the system tested for trouble code's? Go to any Kragen or Autozone and ask for a OBD 2 trouble code test, it is free, record any code's that show and post them back here on this same thread.

try a new set of plugs, wires, and fuel filter. full loaded tune-up. air filter too.

May also be mass-airflow sensor if equipped. does it display a Check engine light?
