My car is stalling!!!
Ok here is the deal!! On warm up my car runs just fine.. after hitting operating temp it starts to hesitate almost stalling(only under throttle)tach just falls..When i floor it just goes dead and then starts to sputter back to life before doing it again....when i take my foot off of it after flooring it will go back to idle like nothing happened. It does not have to be at full throttle to do this.
Iam leaning toward a fuel pump.

yea, the s5 OMPs are pretty sheitty.... but if it were the OMP causing it to limp out two things would happen:
1) a CEL would be thrown
2) the car would be limping until you restarted it.
That's what happened when mine went out.
Sounds like some hardcore hesitation man, I would check all the grounds, especially the ECU, and then take a look at those secondary injectors; check the electric connections, check the rail, check how they fit.

Yea also thought the fuel pump could be the culprit...but that would rule out it doing it on the highway and then going back to normal like nothing happened. Maybe???
Also if i keep the throttle at the special spot it will drive but the wideband is showing lean as hell!!!!! 16 plus!!!

yea, I thought that was confusing... on the s5's the pulsation dampener is integrated onto the fuel rail. It absorbs pulsations in the rail from injectors opening and closing.... keeping the rail evenly pressurized. I'd check the secondary rail as being the primary culprit here, but indeed check the primary injectors as well.
