When it gets to 20 mph bougs down acts like no fuels of something

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your 2006 Jeep Commander acting like it's starved for fuel at 20 mph could be pointing to a few possible culprits. It might be a fuel delivery issue—like a clogged fuel filter or a failing fuel pump—that’s limiting the flow when under load. The fact that it revs fine in neutral suggests that it's more of a fuel or air issue than a mechanical one. Another possibility is a faulty Mass Air Flow (MAF) sensor or Throttle Position Sensor (TPS) that’s causing the engine to stumble under load. These sensors tell the engine how much fuel to mix with the air, and when they misbehave, it can feel like your Jeep is gasping for breath.
