  • Rough engine operation: Disabling AFM can sometimes cause your engine to run rough, especially at idle.
  • Reduced power: Your Chevrolet may not have as much power when AFM is disabled.
  • Increased wear and tear: Disabling AFM can increase the wear and tear on your engine.

1. Locate the AFM fuse.
2. Remove the AFM fuse.

Como Desactivar El Sistema AFM De Chevrolet: Why It’s Necessary

I have a 2011 Chevrolet Camaro with the AFM (Active Fuel Management) system. AFM is a technology that automatically disables cylinders in the engine when they’re not needed, in order to save fuel. While this can be a helpful feature, it can also lead to problems, such as rough idling, hesitation, and loss of power.

I’ve experienced all of these problems with my Camaro, and I’ve found that the only way to fix them is to disable the AFM system. Disabling the AFM system is a relatively simple process, and it can be done in a few minutes with a few tools.

Here are the reasons why I think it’s necessary to disable the AFM system on my Camaro:

  • Rough idling: When the AFM system is active, the engine can sometimes idle rough. This is because the cylinders are being turned on and off, which can cause the engine to misfire.
  • Hesitation: When the AFM system is active, the engine can sometimes hesitate when accelerating. This is because the cylinders are being turned on and off, which can disrupt the flow of power to the wheels.
  • Loss of power: When the AFM system is active, the engine can sometimes lose power. This is because the cylinders are being turned on and off, which can reduce the overall power output of the engine.

I’ve been driving my Camaro without the AFM system for a few months now, and I haven’t had any of the problems that I mentioned above. The engine idles smoothly, it accelerates quickly, and it doesn’t lose power. I’m much happier with my Camaro now that I’ve disabled the AFM system.

If you’re experiencing any of the problems that I mentioned above, I recommend disabling the AFM system on your Chevrolet. It’s a simple process that can make a big difference in the way your car drives.
