bug zapper sound??? My injectors???

[drewstealth94]

I hear a wierd buzzing sound that sounds like a bug zapper, but not as loud. It sounds like it may be coming from my injectors. Do you think it is possible for the injectors to make this sound and if so what does it mean? Do you think it can be causeing my phantom knock?

could be your spark, ive had this happen to me where the spark wire was loose on the coil, also could be your lifters clicking. its nothing to really worry about unless its excessive, you should maybe only hear this when i idle. i simply just cleaned mine.

Pop the hood after dark with the engine running and take a look. Then tomorrow, you can get a new set of plug wires.
