So I recently was working in the engine bay installing a set of grounding wires and the big3 wires.

While running an alternator wire underneath the intake, it contacted metal and shorted against something.

Could that have fried the Intake Manifold electricals?

I ask because now I have an idle and running rattle similar to in this video..

It sounds like it's coming from the belt area, but I could be wrong.
Immediately after my mods, I didn't notice this, but about a day later, I did notice the rattle. As the engine is faster on the highway, the rattle speeds up and eventually gone.

Thoughts?
