Oldsmobile codes

P0113 is Intake Air Temperature Circuit High Input, Internally failed IAT sensor Faulty connection at IAT sensor Open in IAT ground circuit or signal circuit Short to voltage in IAT signal circuit or reference circuit IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.) Faulty PCM (less likely but not impossible)

P0172 is Fuel Trim System Rich Bank 1, Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Faulty Mass Air Flow (MAF) sensor

P0304 is Cylinder # 4 Misfire,
Known Failure Points:
1. Plugs- specifically Bosch Platinum plugs tend to self-destruct
2. Ignition Control Module- Kinda a "go" or "no-go" type thing. When it fails, you most likely won't be able to start your car.
3. Coil Pack Housing (usually white, some aftermarket are black) - Seems like an unlikely part to go, but from what I hear the plastic can breakdown and cause crossfiring.
4. Coil Pack- Haven't had a bad one yet, but it's entirely possible.
5. Plug Boots- If they're old, they might dry out and crack due to the high heat they are exposed to. Again, not very likely, but when all else fails.

Changed mass air flow sensor now keeps stalling

Indeed, I'd be for recovering the original MAF sensor and cleaning it. One VERY important part of cleaning is to NOT use Acetone or anything similar that would cut through the "varnish" coating from it's calibration days. Use Isoproyl (ordinary rubbing alcohol for cleaning). Clean with a Q-tip and if any fuzzy cotton fragments get hung up inside, simply blow them out OR remove with tweezers. Re-install and you'll probably be better off than with a replacement. To expound further on the varnish matter. . . they're (MAF sensor) calibrated during manufacture WITH the varnish in place. Removing that coating often renders them useless thereafter. Most common symptom of MAF sensor problem is sluggish acceleration to eventually VERY sluggish acceleration. Hope this helps some. . . and thank you for trusting Fixya'

Locating MAF on 2001 alreo

Honda's do not use a mass air flow (MAF) sensor. They use a manifold air pressure (MAP) sensor. The MAP sensor measures vacuum vs the MAF sensor measuring air flow/temperature. No real reason to clean a Honda MAP sensor. Are you having engine performance/idle problems? --------------------------------------------------------------------------------

Car stalling

How old is the air filter? Replace if dirty. Did you adjust spark plugs to correct gap when installed?

Check sensors, particually maf sensor, may need replacing or cleaning. Maf sensor is located on the intake pipe from the air filter. Can buy the cleaner on eBay, 'maf cleaner'. The maf sensor measures air flow telling the injection how much fuel to use.

Also if there is a crank or flywheel sensor, check it's ok.
