Knock after grounding kit install?
I just installed my grounding kit today on my 03 auto max, and everything went smoothly. I started the car and still, everything seemed fine. However, upon acceleration there is now a slight knock coming from the engine bay. Anyone have any clue what could cause this?

Definitely nothing to do with some extra grounds.
Perhaps it's something you're just noticing but has done it for a long time.

Figured it out. It turned out to be a bad throttle body ground. Once I took it off, no knock. Once I put it on, knock. I've got no honest clue how that happens, but anyways, found a new ground point on the throttle body and so far no knock.

Can you take a vid?
You mean the new ground is actually making it knock?

It WAS making it knock. With the new ground point on the throttle body it no longer knocks. And I'll try to get a vid

Please take a picture of the new ground points, both on the throttle body and the other end.
