Why is my 2004 mazda 6 losing power when i push on the gas?

There are several reasons why your 2004 Mazda 6 may be losing power when you push on the gas.

1. Faulty Spark Plugs: Worn-out or damaged spark plugs can cause the engine to misfire, resulting in a loss of power.

2. Clogged Fuel Filter: A clogged fuel filter can restrict the flow of fuel to the engine, causing a loss of power.

3. Dirty Mass Air Flow (MAF) Sensor: A dirty MAF sensor can provide incorrect readings to the engine's computer, resulting in insufficient fuel delivery and a loss of power.

4. Faulty Oxygen (O2) Sensor: A faulty O2 sensor can provide incorrect readings to the engine's computer, affecting the air/fuel mixture and causing a loss of power.

5. Failing Fuel Pump: A weak or failing fuel pump may not be able to deliver enough fuel to the engine, resulting in a loss of power.

6. Blocked Catalytic Converter: A clogged catalytic converter can restrict the flow of exhaust gases, causing a loss of power.

7. Vacuum Leaks: Vacuum leaks can cause the engine to run lean, resulting in a loss of power.

8. Faulty Throttle Position Sensor (TPS): A faulty TPS can provide incorrect readings to the engine's computer, affecting the air/fuel mixture and causing a loss of power.

9. Transmission Issues: Transmission problems, such as low transmission fluid or worn-out clutches, can cause a loss of power.

10. Engine Mechanical Problems: Engine mechanical issues, such as worn piston rings or damaged cylinder heads, can also cause a loss of power.
