Engine knock normal?

[68 Grand]

Go to 11:24 in the video. Even though he's talking, you can hear that the engine isn't producing that knocking sound.

Alright, the dealership just called. They said that they ordered a new vacuum pump. I am hopeful. Quickly, I searched YouTube and this is what I found.

That sounds exactly like it. I am hoping that the replacement part will solve the issue. I will pick it up tomorrow and report back.

Oh, and btw, I only use high octane fuel from top tier stations.

All fixed. Bad vacuum pump.
