P0103 OBD-II Trouble Code Technical Description Mass Air Flow (MAF) Circuit High Input What does that mean? Basically this means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF circuit had higher than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0104. Symptoms You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness. Causes A code P0103 may mean that one or more of the following has happened: The MAF may be disconnected, or a wiring connection may be bad The MAF sensor may be damaged The vehicle computer may be faulty (very rare) Possible Solutions The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures: Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Inspect for any air leaks near the MAF sensor. Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.

1996 buick le sabre code P0102A stalling engine
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0102 may mean that one or more of the following has happened:
The MAF may be disconnected, or a wiring connection may be bad
The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
The MAF sensor may be faulty
The vehicle computer may be faulty (very rare)

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.

I would start with the cheapest and easiest repair first which is to replace the spark plugs first and then clear the codes and see if the other codes come back up again. Sometimes one problem will cause a host of other issues, so do the cheapest process of elimination first.

Make sure that there are no leaks, on your duct hose..where the MAF is located..because if you are getting too much air..the MAF, will try to adjust to it, and it will throw your injectors out of wack, and then you will have a code...stating that you are running too rich, or lean, and then your plugs will foul out, because of too much gas, or not enough...and then it will trickle down to your O2 senors..it's a big chain reaction when it comes down to the MAF sensor...but check your Duct....

Vacuum leak somewhere.
Possibly could be the O2 sensor (the one before the cat up front).
I'd search for a vacuum leak since you may have rattled something loose.

It sounds like they have got the distributor out of time. You will need to adjust the distributor. That is what it sounds like.
