Hi,
i'm attending button willow on the 20th and i ran into this problem:

my car when i started it up today right the idle was fluctuating and so was my vacuum gauge (indicating a vacuum leak)
and then i checked everything that i could see which appeared to be fine
and then so i took it for a spin (warmed up and all) and i hit 10 psi in 1st gear and let off then drove some more like normally...
and the car makes a NASTY scream now
and the only time the scream squeeling goes away is when i hit boost
which makes me think that it's a vacuum leak that got enlarged, do u think i'm correct? or internal blower damage? but if it was internal, would'nt u think it'd be louder at boost? i hope it's a leak, and that the shop can fix it tomrorow cuz i leave tomrorw nite for buttonwillow any ideas suggestions?

 

anyone?
