I've been getting a humming sound from the engine compartment and it seems to be happening more and more often. I get it either after initial start up or when removing my foot off of the gas pedal. I'm guessing it's comming from the TB and is caused by some kind of vibration when the blade is fully closed and the eaton is still trying to suck in some air? If I tap the gas it stops immedietly. Anyone else have a problem like this, anything I can do to remedy this? It's starting to get obnoxious :shrug:
