Why does the GM MAF sensor get Fuzz?

Why does the GM MAF sensor get Fuzz?

Because this MAF sensor is a hot wire sensor type that easily becomes contaminated with dirt and stuff if the air filter isn’t performing its job. This contamination will appear as a type of ‘fuzz’ on the two wires of the sensor.

What does the p0103 mass air flow code mean?

P0103 Mass Air Flow High Frequency. Lean and/or Rich code (s). Fuel Trim code (s). A tremendous lack of power upon acceleration. Black smoke coming from the tail-pipe. Vehicle may idle rough and stall.

Can a car run without the mass air flow sensor?

The mass airflow sensor is a key sensor in your car. Your car has a lot of sensors, and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor? In this article, we will look at what happens when you disconnect the mass airflow sensor.

What is the fuel pressure on a Vortec?

Dude, 150 psi of fuel pressure is extremely high, perhaps even impossible. I would suspect your pressure gauge. Dead head pressure may reach 100 psi. These vortec engines are well known for injector/poppet valve problems, so you may want to consider the upgraded injector assembly that eliminates the poppet valves.
