1997 honda civic ex -gas mileage

my gas mileage has dropped 40% in the last 2 weeks. When i drive the car and press the gas sometimes it doesnt respond, it acts as though the gas has finished and then suddenly revs up.

any ideas what i need?

oxygen sensor, fuel filter causing the mileage to drop so much?

thanks

PS I changed the plugs, wires

Here are some illustrations of the PCV valve's location that might help:
