Bogs down around 4,000-5,000rpm won't go any further...

I was out driving tonight and I decided to open up the throttle.
It accelerates fine and then bogs down bad; I shift.
Pull over right away and check for fuel leaks.
(I could smell fuel from inside the car).
No leaks anywhere.
Checked all the fuel lines, under the car, the PD, etc.
So.... I thought maybe it was just a one time thing...
It wasn't.
Doesn't matter what gear I am in 1st,2nd,3rd.
It will rev fine in Neutral however.
Ideas?
lol.
No cat. New filter, plugs, wires, etc. Just put the engine in about two weeks ago; 1,000 miles almost. (It was ran about 6 months ago, not a new rebuild).

accelerator pump same thing happened to me pull the air filter assembly just under your choke there should be a little nossle that spays fuel down the barrels check it out could be a problem there or else it could be an electrical problem the wires running into the carb on the drivers side control it
hope your car has a carb or this may not help

No carb on a s5?
I wish there was so I could just do what you described; guess I should've said that.
It is a s5 n/a
