I hope i can find some help, I've replaced coils and given it a complete tune up. The car turns on fine and idles great, when in park, I hit the gas and the car revs up fine. When I try driving it, in any gear, it boggs out and doesnt respond well. The engine dosnt rev up like it would in park. Please help my next step is checking the fuel pressure, could that be the problem? Cause it revs up really good in park!

Lack of acceleration,chugging,hesitating,bogging,misfiring etc. could be caused by one of the following below:

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it.
