Rough idle, random misfires, power loss and a code that says vacuum leak on bank 1

Hello, I'm Danny.

We really need the code information. The best thing to do is perform a CAN scan on all the computer systems on your car. Here is the tutorial on how to perform a CAN scan:

Once you perform this procedure we then ask you to get back to us with all the code information and we can then properly diagnose the issues on your car including a vacuum leak. Hope this helps and thanks for using 2CarPros.
