Image Note:
The image above shows AFM #A31-060-001 which uses 3 mounting bolts. The AFM for your exact car may appear slightly different depending on year and model number.
Description:
Air Flow Meter model number must be supplied to order. MSA Air Flow Meters are rebuilt on genuine Nissan cores.
Core Note:
Your old part (core) must be complete as pictured above, including the plastic cover (does not need to be attached, only included), and in rebuildable condition. The mounting bracket is not included in the rebuild, so you do not need to send it in (it will not be cleaned if you do, so we recommend not sending it).
Note:
Be sure to follow the Factory Service Manual testing procedures fully and carefully to confirm that your metering device is actually the cause of the problem you are having. As with all electrical and smog parts, there are no returns on these metering devices if it turns out that they were not the cause of the problem with your Z or ZX.
A Note on Air Flow Meters:
Over the years, a common trend that we have seen is defaulting to the Air Flow Meter as the source for why a fuel injected Z is not running properly. In many cases, someone will replace an old AFM with a new or rebuilt unit, only to have the car run even worse than it did with the old unit (or not at all). This situation comes up most often when the car is running rich (too much fuel). Typically, when this happens it is the result of another component functioning improperly, such as the (Water Temperature Sensor). AFM adjustments are often used to "band-aid" other issues in the fuel injection system, and in many cases we find that the meters are adjusted to the full extent possible. Once no further adjustments can be made, it is usually determined that the AFM has gone bad and needs to be replaced. When the replacement is installed (which is set back to factory specs), the fuel computer will try to push far too much fuel through the injectors and the car will either not run at all or will barely run extremely rich (exhaust backfires, black smoke, etc.). Before ordering a replacement Air Flow Meter, it is highly recommended that you fully inspect other components in the fuel system (in addition to the required Factory Service Manual testing procedures) in order to rule out other probable causes. Items to inspect include the water temperature sensor (75-79)/head temperature sensor (80-83), fuel injectors, all of the electrical connectors throughout the system (injectors, temp sensors, air regulator, etc.), fuel pressure regulator, spark plugs (for plug condition), and more (give us a call at (800)-633-6331 for other possible causes).
