Friend just installed ls6 intake throwing code
Yes. You are correct. Vaccuum leak is the culprit. Make sure the gaskets are all good and that the intake is torqued properly. Also, make sure all vaccuum and PCV hoses are connected and routed properly.

So im thingking its the gaskits Try using some carb cleaner spray and spray some around the area of the seal, one area at a time, and if there is a short change in engine RPM's, then you've got a vacuum leak at the area you just sprayed.
Check all of the hose, even at the power brake booster. Did you check your MAP sensor, Throttle body, etc ?
Good luck

That makes sense...air was getting in without the MAF sensor seeing it, and the O2's were forcing a large correction hence the code. If the car were speed density it wouldn't have thrown the code...which would make it harder to know there's a vacuum leak.
I have yet to start my car since the my swap i need to send out my tb for porting still, but i reused the gaskets on it. came off a 30k mile z06 gaskets looked pretty good, how many people reuse the gaskets?
OK got the 2nd intake install over with now..
let it warm up, took it out and drove a little bit , no codes but still runs a little rough.... would this be the computer trying to relearn everything from unplugging the battery, and if so how long does it usually take ?
THANKS for all your replys

My suggestion to anyone installing a used LS6 intake is to install new gaskets. Once the intake has been put onto a car the gaskets conform to the torque specs and the heads of that specific car.
