Thanks so much! I tested it just like in the video you sent me and that is exactly where the noise is coming from. Do I need to have this hooked up to the car or can I take it off and run the car anyway? I want to remove it so that I can fix it then put it back but I still need to drive the car

@tjts1, sorry for the headline. It is really annoying when I start the car. what would you have put as a headline?
