09/07/2021· Often if an air filter is not installed properly, or the air filter box is not closed, a piece of debris can get sucked into the mass air flow sensor (see this photo) and cause problems. Sometimes the debris can fall in during the air filter replacement. In this case, the repair is easy. The mass air flow sensor must be cleaned and the air filter must be reinstalled correctly or replaced.
29/10/2007· mass air I appreciate all the info, it helps alot. I am going to go mass air. I figure I will get the computer from autozone, 93 stang w/manual trans, wire harness from fordfuelinjection, mass air sensor, and a chiltons book with the wiring diagram. I just hope I get it hooked up right so that the tuner can hook to it properly.

I have some cheap 100 piece security bit set from Harbor Freight for like 7 years ago. Enough different types of bits to work on most "security" screws.
The air is then mixed with the fuel, and combustion is the result. This is what propels the car. There is a sensor on the air intake called the mass air flow sensor. This sensor calculates how much air to mix with the fuel. If you are using a cold air intake, the MAF sensor might not be calculating properly. This means you are not getting the ...

The mass air flow meter mounts between the air filter and throttle body, and consists of a pair of small wires located within a calibrated housing. One wire measures the temperature of the ambient air, while the other wire is always heated to 200° greater than the ambient or "cold" wire. The amount of air flow through the meter and the temperature of the air results in cooling of …
16/12/2017· Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.
The mass airflow sensor measures the volume of air moving through the air intake system. The sensor, also called a MAF sensor, is usually secured to the air intake tubing that runs from the filter to the fuel injection system. If your vehicle starts to idle rough, or it stalls while you are driving normally, you may have a problem with the MAF sensor. The first thing you''re going to need …
