Hissing sound, need help I have a 98 TA and just installed Pacesetter LT with a TSP ORY. I have checked all the clamps and there are no leaks, i have checked and tightened all the header bolts along with the egr and air bolts, but i am still getting this hissing noise. I only hear it when accelrating,not while idling. I didnt hear it much on the first day, but now i really hear it. I used restrictor plates for the AIR, can the smaller hole be whats causing the hissing/wissling type noise i am hearing, or can it just be an increase in valve train noise? I dont hear any tapping or knocking, it is consistant with the rpms, it's always there, and i have lifted the car and checked for leaks a few times with non to be found. Any assistance would be apreciated. Also, i dont have any vacuum leaks.

But, if you don't have the means of erasing/removing that code, then just bolt the system back up the way it was originally set up. This way you can remove the hissing sound and I doubt the AIR will "burn out" as quickly as you think. And if it does, then you can pay the small amount of money to delete the code(s) for AIR (or even pay nothing if you know someone with HPTuners or something of the likes). Either way, take the restrictor plate off now, that is the only thing causing you trouble at this point.
