After having the engine swapped out. Several electronic components started buzzing. The electronic controlled intake the coil packs I think it's a vapor lock as part of the vacuum lines. I'm not sure what the part is and a couple others are buzzing. The coil packs are good the other parts test good the computer is reading no error codes other than a random misfire. We know that the security module has a part to play in this but it's not only that.

Hi,

The coil packs are buzzing? Can you take a picture of the other thing you aren't sure of that is buzzing and upload it for me to see?

Honestly, I'm not sure where to start simply because the coils buzzing is odd.

Upload a picture for me and hopefully, I will make a connection between the two issues.

Take care,
Joe
