I have this weird hiss/whistle that is coming from the front of the engine manifold area. Its relly hard to tell over the exhaust / engine sound but everytime i look at it i get the feeling the hiss is coming from the fuel rail area.
I have purchased a vac gauge and connected it to my manifold (in place of char canister) and it swings from 16-17 Hg @ warm idle. I am not sure what its supposed to be but that seems a bit low to me. The manifold bolts are tight (just installed new apn exh header) and the vac hoses seem to have no effect when i disconnect them and block their inputs.
For the most part the idle is ok, hick up here and there but i guess acceptable. Should i test the fuel pressure next ?
