Hi all, I'm extremely new to this forum but I didnt have nowhere else to go for help. I have a 1997 grand prix gtp with a 3.5" pulley and a cold air intake. I can't drive the car now because it makes an absolutely awful noise that sounds like it's coming from the intake but it's not the supercharger I just replaced it. This noise had happen before I replaced the gaskets underneath the supercharger and I still did it, I replaced some vacuum lines and it stopped! After about 2 and a half weeks it started again. I replaced the supercharger thinking that was the problem but it is STILL making that noise and idling high (around 3000rpm) and I have no idea what it could be. I asked a local mechanic he said sounds like a bad vacuum leak but I have no idea where to start plz help!!
