Ok guys been gone for awhile but Im back now! The problems I am having are Im losing break fluid back have not seen any on the ground. I assume I have a leak and some air in the lines being the clutch gets weak at times until I pump the pedal. The other issue I am having just started the other day, I have noticed that I am only boosting up to about 2.5 or 3. The gauge is starting off at negative 18-29 on the vacuum side. Is it a bad gauge or do I have another problem and if so how can I go about checking the issues I have stated. Thanks in advance for any help suggested!!!
The car is a 2006 Cobalt SS.

 

For the leak take a look inside the rims and wheel wells for oil spots,also is any showing up on the back of the car.

If the car feels the same on a pull I would think its the gauge.

 

if the brake fluid has been dropping slowly for a long time its probably just your brake pads wearing. as for the boost issue, are you still making about the same power? if so its definitely the gauge because 2-3 psi would feel very very slow

btw coblasts you seem very knowledgeable could u possibly help me out too?

Yea the car does not seem to slow but you know how when u start over analyzing things everything seems as if its not as good as it once was.. tried the by pass mod and there was no change!! Thanks so far guys

 

hey numb nuts bring your car to me one day and ill look at it for you!!!! lol

 

I can do that it starting to need some love... Where should i start as far as the boost problem? Sorry I have been gone for so long I had some family issues to deal with!! Thanks for the replies!!

 

first off start with your leak ( if you cant see it anywhere look at the back of the rotors/rims to see if you see it streaming. Now check the master cylinder (Which is the more possible cause) the clutch issue is a known lsj issue ( if you get on it you need to push the clutch down a few times because of the pressure plate teeth and the t.b being ****). Once you find the issue resolve your issue with the boost i doubt the boost is gone, i say gauge. i havea mechanical gauge as well.!!

 

What is a ggod replacement gauge that just drops in and uses the factory wiring and such.. Im not looking for a high dollar one just a direct replacement from the likes of autozone or advanced auto so if it doesnt fix the issue i can return it... Im going to try and dig into these issues by the weekend!! Thanks for the help

 

Dude.... The only one will be a autometer gauge. The same one...... Because of the fact its electronic and its set on perameters. Use a mechanical gauge...... I have one ill sale its a autometer

 

How hard is it to hook one up? What all has to be fabricated? Thx

 

Just a t, along with copper line or nylon line. ...

 

where do u run the nylon or copper where through

 

With a t to the direct vacuum source

 

Heard some rattling at idle today sound like it was coming from the bottom of the engine not sure, did not sound like that when i got home just every so often.
