You have something seriously crapped out from the sounds of it.

I would start by opening the distributor cap and seeing what the posts
and rotor looked like.

Then I would be opening the air filter to see if it is plugged. If
blocked with oily dirt, suspect plugged rear CCV tube or grommet hole.

Next I would be pulling the plugs to look for a really clean or dirty
one.

If clean suspect too much gas or a bad injector, if really dirty,
suspect electrical.

Pull the dipstick... smell the oil.. smell like
gas? Bad. Fix raw fuel problem, change oil.

Put fuel pressure gauge on fuel rail... start
engine... stop engine. Fuel pressure go
down? Bad. Fix injector.
