So I drove my car for the first time in two weeks yesterday.

It ran 100% fine before this

Idle surges to 3k rpms and will drop down and surge back up. There is a whine so loud it will piece your ears coming from the right side of the supercharger near the air intake.

Wonder if anyone has any ideas. I have torn it apart yet as its currently -1 outside

has to be vacuum leak or bypass valve issue at the TB

My thoughts also... check the line in the front for the IAC (I think it is) if not make sure the bolts are tight holding the tb to the s/c.

on a funny note, I started my car up the other day after finally getting my s/c back, revved it up and was hearing some god awful sounds comming from my motor, I only had tightened up one s/c bolt... oops

will definatly check these out but right now it can sit its -12 out :(

glad its something easy so I can focus on my mods stage 2 :)

Oh Also im keeping the car, I just bought another and this one turned into my weekend warrior

Im uploading pics now www.x-vent.net/car

gt35r whipple

all im going to say im not starting some huge thread i dont know if i can find a happy medium using both but I have both in my garage turbo header being made now.

Gotta love promotions at work

Interesting;) :cool:

yea im either going to completely screw this motor or it will put down some serious numbers. I have got to send the whipple to get refurbished or w/e you call it. I picked it up second hand. You try getting whipple to sell you something its ridiculous.

How the heck did you break those intake bolts? Too tight?

So now you have 2 cobalt SS?

na, i bought a truck for daily use

I would like to know that too.

they were at spec, I also tore apart a tranny mount dam thing shattered, some of the drive line parts just dont hold up unde rpressure :(

Oh well Im taking this bad boy to the dealer to get a new transmission linkage and get them to replace the bolts and pcv valve (i belive thats what it is)

I love my warranty :) oh yea just got it back again! w00t screw dealer world
