Injector noises

[96bmwm3]

I’m not that much of a new-B here, I’ve heard injectors click, but recently it sounds more like electrical arcing or similar coming from my injectors. Any thoughts? Is this normal?

BUMP - Any thoughts? I'm used to hearing a rapid, very distinct *click* from an injector, but these are making sounds similar to arcing. Are the injectors bad? I seem to only hear it at idle...

I thought it might be spark plug wires at first, but after replacing those the sound was still there.

I wish people could answer these.. I think its normal. I replaced my stock 420a injectors with 440's it stoped clicking. You may ask why 440's. I was turbo'd made a huge diff.
