Question High idle after top end clean and AMW catch can install?

I'm at 1500rpms when I come to a stop and it takes about 5 seconds for the idle to drop back down. I have driven the car about 250miles this way.

It should relearn itself. But it seems it should have done that by 25o miles. My car did that for about a week after the LS6 intake install.

Did you create a vacuum leak while installing the catch can?

The only vaccum leak I created was when I pulled the brake booster to pour in the cleaner. I had a couple of inline fuel filters after the pcv before,so installation of the catch can was even easier.

Sounds like a vacume leak to me.
