So, the acceleration will begin hesitating because the engine is lacking an adequate flow of fuel. This is the result of the engine not receiving a steady flow of gasoline to accommodate your acceleration demands. When you step on the gas pedal to accelerate the vehicle, you may experience hesitation as you are moving forward.

It may send accurate airflow information to the engine control unit at first, but then it will stop doing so shortly after. This symptom may occur if your mass air flow sensor is just starting to go bad. But if the engine begins to stall shortly after, then it is obviously isn’t.

When you start up your vehicle, and the engine turns on, you may think everything is fine.

This will cause the engine to simply not have enough power output for the current demands. This means that more gasoline and air will be required in the internal combustion chamber.īut if you have a bad mass air flow sensor, then you will likely not get enough gasoline to accommodate this load. Whenever you increase the load of your vehicle, it will put more demand on the engine to generate enough power to sustain this weight. If the engine is going to successfully turn over, then you need to correct this problem so that the spark plugs can ignite the proper mixture. This is understandable with a bad mass air flow sensor because it will cause the internal combustion chamber to have an inadequate mixture of air and gasoline. When you put your key into the ignition and twist it, you may find the engine is difficult to turn over or start altogether. This will ultimately hinder the performance of the engine. Meanwhile, there is very little gasoline being burnt in the process. The “lean” word refers to the abundance of air and not enough fuel. When you have a lean idling problem with your engine, this is the result of too much air and not enough gasoline getting mixed together in the internal combustion chamber. Sometimes these symptoms may be due to other reasons, but you should still have your mass air flow sensor inspected if you experience at least a few of these symptoms that are listed below. You just need to be able to recognize the symptoms as they occur so that you will know to associate them with a possibly faulty mass air flow sensor.
#CORVETTE MASS AIR FLOW SENSOR PROBLEMS MANUAL#
Each system is backed by a limited 90-day warranty.Įlectrical components such as sensors are non-returnable parts.Īlways refer to a factory service manual when diagnosing engine service problems.A bad MAF sensor is fairly easy to detect from the very beginning.

Installation occurs in 10-15minutes using basic hand tools. No other mass airflow sensor available gives you this much control. Engine running too rich or too lean? No problem!! Just whip out a screwdriver, give the calibration screw a twist and WHAM!!, problem solved. The sensor provides up to 30% more airflow than the standard OEM unit, and you don't have to tear out the screen! The Granatelli Motor Sports Adjustable Mass Airflow Sensors come equipped with a calibration screw builtright in. This unit is the only mass airflow sensor that features fully adjustable calibration, so high lift cams, big valves and larger intakes are no longer a tuning problem for performance enthusiasts. If you have a highly modified 1985-1991 TPI Corvette, then this is the sensor for you.
