Hi, van has very little power under any kind of load, going up even a small incline. Feels like engine isn't getting enough fuel. When gas pedal is pressed too much the engine makes a loud roar, and it sounds like the venturies are wide open, trying to make power, but there's nothing available. I have to feather the gas pedal to get going. Fuel pump/filter assembly is brand new, gas tank cleaned, new cap and rotor.

is check engine light on ?

check fuel pressure
check for codes if any
check timing
check exhaust back pressure (checking if catalytic converter clogged )
if all good
disconnect the O2 sensors and give it a try drive around and if you all better replace O2 sensor
DO NOT use a universal O2 on your truck it will not work correct
good luck and let me know
