Ok So I just purchased a new MAF sensor and CamShaft Sensor and installed, Still stumbles, no power, throttle weak and rough idle. Other parts i just replaced and rechecked multiple times. New Wires, New spark plugs, new coil packs, new injectors, checked fuel pressure and is constant 52 PSI at idle and wide open throttle, new EGR valve, new air filters, new oil change and filter, new Bosch oxygen sensors, New seal on air intake, removed throttle body cleaned, oiled and replaced with new gasket. I removed the entire exhaust no plugs in exhaust and reinstalled. Any other suggestions? I am uploading a youtube video so you can hear the car. I will load the link soon. I am running out of ideas here.
