TPS out of calibration, since you have a s4 also check the dashpot while you are calibrating the TPS. Leaky injectors too will cause it, but make sure to cover the basics too.

You need to search the forums for TPS adjustment it has been covered many times and I am not about re-write the procedure again (nothing against you). The dash-pot on your s4 is located on the throttle body. Most likely you need to check both according to the factory service manual. This doesn't rule out the fact you should service your old injectors...
If it's not idling properly and backfiring like crazy and you can't rev it past say 4000rpm, I would check your air flow meter connected behind the air filter also. You definitely want to go through that service manual and start checking up on those components.
