Anyone has that buzzing sound that last for like a second when the engine is turned off? its like a bzzzt sound somewhere on the head/valve cover area and its not loud but can be heard when your is hood open.. its like an electronic sound

 

ur not auto are u? how long is the buzzing on for?
thats ur throttle body not closed all the way.. thats what happened to me when i had the FIC and it drained my battery but i thought it was an auto only problem

 

i have a standard, its only on for about a second or less and its not loud and can only hear it if you stand close the engine bay.. like engine off.. bzzt (electrical sound) and then gone

 

Sounds like the DBW still getting power.

 

is it something normal though? i hear it pretty much everytime i pop the hood and turn off the car.. i thought it was the ignition coils due to the electrical sound it makes lol

 

o well this is the problem i had when i was with the aem fic for some reason.. it gave me that electrical buzzing sound and then my battery would die at monthly intervals but my sound stayed on forever.

 

Yes, normal. I forget what it's called, but it's explained in the owner's manual, everyone should expect to hear it once in a while.

 

hmm perhaps i should open the manual lol, but where does it really come from?
