i put race style headers on and took off the EGR/AIR but i dont see the vacuum line im supposed to plug.. and since ive been driving it it sounds louder under the hood like air is coming in or escaping. but i dont smell exhaust inside my car or from the engine.. so that rules out a header gasket leak right? i was thinking since i never capped that hose is it making all the noise? or could it be my belt cause it has been squealing lately.. any help or pics will be appreciated in locating this vacuum hose fiend!

 

oh its not tuned either so i dont know if that helps the noise either..

 

I think you only plug the egr out of the intake I could be wrong you need to take the airpump fuse out and that will kill the air sound I belive.


BTW get that thing tuned or you will regret it.

 

Oh really? why is that? i ask because i thought it would be safe to wait. some guys on here even said i didnt have to unless i did a drastic change like cam or something..
