jesus christ...got all that money into your interior and you cant buy a $40 boost gauge and hook it up. that will tell you 100% if you have a vacuum leak or if you're not making 'full' boost.

Did you find rubber T's I have been looking all over the place for some or are you using the hard t's?

Thanks Nick #2 Always forget about the stealership when it comes to little parts like that.

What's the bbv solenoid delete and what's the purpose if you don't mind me asking.


And to the OP if you took the throttle body off or whoever installed the headers took it off, I'd remove it again and make sure no old gaskets jammed between mating surfaces.

i bought rubber T's at autozone too.

I buy them from the dealer because the one form the BBV all the way back to the MAP is only $18. Saves a lot of headache too because it comes with all new plastic lines and rubber fittings...I then lubed them just to prevent future dry rotting...or at least dry rotting as fast as most of them do. It's just as the saying goes work smarter not harder...

My bet is TB gasket.

why do you say that? i have a brand new gasket


and To Nick (Blue) i went to price check that Vac line and it was 30$ with the Rubber T's from the dealership. Aren't the ones GM sells (plastic Vac lines) really ****ty? i know my original ones broke when i was installing my LIM gasket a few months back.

buy a $4 can of carb cleaner and find where the leak is!

:th_sign-withstupid: check for the leaks before actually throwing parts at the car

how can i use that to find the leak?

Spray it around the engine and when the leak is found the idle will go up. Please read stuff... It has been stated time and time again.
