My problem is that when I start my car and go its fine than in about a minute or two it starts bogging and loosing gas feeling like its not getting enough gas into the engine, I dont no why this happens. It almost like shakes and feel slike it has no power. I checked the fuel pump and it gives gas so im not sure what else it could be. Maybe something with my cold air intake not working properly.

Check and test all the following below:

Oxygen sensor
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)
Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
