Unhappy Help!!!!!! Please!!

i was noticing a a slight rough idle and i didn't think anything of it car ran great.
today while at a stop light i took it out of gear and punched it....and it studdered from 500 to about 2k then reved quick
got out on the road and punched it....ran great. then i stopped and got some gas pulled out punched it it kinda though about it for a second. then i got on a side street and just put the pedel to the floor and it did nothing!!!!!!!!!! just sat studdering and took it a good 5 seconds to pick up and go. then i pulled in my house popped the hood and i smell oil and see SMOKE!!! i see no signs of where the oil is coming from no leaks anywhere on the car that i can see from the underside or under hood!!!! HELPP!!!!

The list of things it could be is longer than my arm. Start inspecting things like wires for igniton or computer for both loose or corroded connections.

Then do checks of the routine things like EGR sticky. IAC, injectors need cleaning, vacuum leaks or intake manifold bolts loose and the like.

Then start testing things like compression and leak down. Fuel pressure at idle and WOT.

After that if you haven't found the problem evaluate what you did see and go from there.

Almost sounds like a clogged fuel filter but that doesn't explain the smoke. Where's the smoke coming from?

under the hood thats why i though it might be the intake leak because they leak oil out the back.

From the rear of the engine? Sides? Front?

just cranked it up HARD AS HELL to get it running!!!
when its running you punch it to quick and its like the engine just cuts off and it will pretty much DIE!

rev it normal and everythign is fine
i held it to the floor and and let it cut off and i saw some smoke once again and smelt LOTS of raw fuel!!!
