Re: Howling intake noise after new intake and TBI
If you open the hood and remove the air cleaner, can you tell if the noise is coming from the TBI?
The reason I ask, is that I also have the performer TBI intake (on my 90 GMC K1500 5.7) and I had some issues with the power brake vacuum hose routing. When you let off the gas, the vacuum will be higher and your vacuum hose to the brake booster may be leaking.
