i took my car to the dealer monday at 7:30 in the morning after 9 hours they call me and tell me that my bypass valve is bad so im like alright. They tell me to come back today thursday so they can put it on, after 4 more hours they call me and tell me to pick it up, and when i do i went down the street and its still only boosting 5 lbs of psi at wot, and now there arguing with me tellin me my car is fine thats normal. so can ne one help me find some gm specs or someting i can show them as proof? i dont know what else to do i mean i love the car i just dont wanna pay for it if its not running correctly................

Bump

 

uh... tell the ******* to go drive another ss/sc on their lot and show me a 5 psi cobalt out there

 

1) it's the dealer, not GM
2) stock should be around 12psi i'm sure there's something that came with the car or manual that says that.

 

retard dealerships, these techs working there, should learn more about the cars they sell there and work on!

its very simple!

 

does anyone know a respectable site that i can print off of so i can so em tho really.

 

www.chevy.com

 

he said a respectable site!

this one should answer questions^^^

 

Tell them to look up Document ID #1522572. It's the Description and operation of the Boost Control System from SI.

 

they had a whole list about what could casue it from iat2 temps to intercooler sensor and nething past 5800 rpm might casue it i dunno what to do

 

This is one of the main reasons I travel over 45 miles to bring my cars to a dealership I trust....lol

And like Kevin said, it's not GM's fault, it's the dealership itsef. Hoepfully there are other more compitent dealerships in your area.

 

ok guys i just got off the phone with my service dept......they think its a wastegate like thing blow off valve stuck open or cracked opened now so the part is ordered......................... i thought wastegates were for turbo but wat ever
