SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

SOURCE: Changed Mass Air Flow sensor, CEL still displays problem

it almost sounds like a fouled fuel injector. this is a tricky problem because it involve so many different operations. the maf is used to deliver fuel and the o2 sensor tells how much. there are 2 o2 sensors one before cat 1 after. mabey check these out visually. the computer should pick these sensors up if there bad. is this a supercharged engine? ill try to come up with some other ideas for you soon.

SOURCE: CODE PO102 after Mass Air Flow Sensor replaced

Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

mass air flow is a small sensor on the pipe from the air breather to the throttle body. Make sure your air breather is clean and also check your PCV valve.

Better gas milage

Want to get a little better performance and increase your gas milage. Remove your mass airflow sensor. Using a pair of needle noise pliers, pull the screen out to increase air flow along with using a high flow air filter or cold air intake system..K&N, Spectra, Varaum, etc. Install a high flow exhaust & Purchase a programmer if you can.

2001 buick park ave high idle

First thing i would do is take the idle air control valve off and clean the carbon off of it and inside the throttle body using a non-chlronated brake cleaner.Then reset the computer with a code reader or a scan tool then start it and if problem still exists take the mass air flow sensor off and spray the thin wires inside the sensor with the same brake cleaner then let it dry for 15 minutes and re-install.Reset computer then start motor.

Sounds like it still has a bad mass air flow sensor or wires to the sensor. Does it still set that particular code? If so then check this component or the wiring to it again. If the sensor is unplugged and the car runs better (default values), it usually is an indication of a bad sensor. Hope this helps

Anytime you make a change to any part of the emissions system, its best to disconnect the
battery for a few minutes. If you don't, the computer retains the fault code and it will usually keep
coming back. When all power is lost to the computer, it will do a complete scan when reconnected
and engine started. Try disconnecting the battery for a few minutes then reconnect and see what happens.

I have a 1995 Volvo 850 wich suddenly stalls mostly when comming to a stop bu can also stall while driving. I have had 3 mass air flow sensors instaled in 1.5 years. The first one seemed to do the trick...

I would check the vacumm lines and intake manifold. any vacuum leak will set a maf code. I done alot of maf codes and not replaced one yet. not saying they don't go bad, they do. also you can remove the maf and clean it, use brake clean, and also clean the throttle body, aspecially behind the plate, use a brush if you have to. this does work alot of times and makes some cars run as if it had a major tune up. Let me know

is the sensor new?
check the wire from the very root of the air mass sensor wiring to the sensor its self.

it sounds like either the air mass sensor is at fault or the wiring is touching somewhere.

Well there are several things that could cause this problem...

1. one of the coils may not be firing.
2. the ignition module could be bad.
3. the mass air flow sensor could be tellign the car to run rich (too much gas)
4. if the car is equiped with a map sensor it could do the same as a mass air flow sensor.
5. fuel pressure regulator could be leaking at vacuum port drawing in more fuel than needed.
6. the computer itself could be bad as well.

The car either has a map sensor or mass air flow not both. The mass air flow would be right after the air cleaner housing usually a 4 wire connector. map sensor is normally located on the rear of the upper intake manifold with 1 vacuum line going to it with 3 wire connector. Hope this helps.
