Tuner says I have a bad vacuum leak.I searched all over for a diagram of stock vacuum system on my LS3 without any success. Can somebody describe the locations or even better a diagram.

Much appreciation!

Do you happen to have an oil catch can installed?

I had a vaccum leak once and it was due to my catch can drain plug not being closed all the way.

In your sig it says you have an Ideal Garage master Cylinder. Start there, make sure the vacuum line didn't pop off and follow some of the lines.

get some carb cleaner or something and spray it on the vacume lines while its running. you'll hear the idle change when you find the leak.

Don't know where all the lines are. I'm am having Hell finding the FSM. Just asking where all the locations are.
