'12 FXDB dying at idle and <20MPH
My FXDB is dying randomly at idle and at low speeds (< 20MPH). It always revs up before dying out but it doesn't always die out when it revs up. The engine dies if I try to open the throttle while its revving. I have to wait until the engine stops revving before I engage the throttle which is usually about 15-30 seconds. When the engine does die, it takes a while to start back up. I usually have to hit the start button while engaging the throttle. I can smell fuel the entire time I'm trying to start the engine.
I thought it was my fuel pak so I replaced it with a spare but it didn't fix the issue. The map is good. I also cleaned the air filter and blasted out the throttle body with carb/choke cleaner. I'm now thinking that it could be a bad fuel pump or the fuel injection is being flooded. Any ideas?

When you cleaned the TB, did you carefully clean the IAC? You have to hit it with a direct shot (I used MAP sensor cleaner, its less harsh) while it opens and closes a bit while the fuel pump energizes. I did it several times. So far, so good.
