![]() As I've become impatient waiting for my intercooler to arrive on my procharger, I decided to get a head start on things and throw on my 30 # injectors and new Granatelli MAF.
Before the new injectors, sometimes I would get what I can only describe as a "spurting" sound under light accelleration. It wasnt that bad and didnt happen all the time. The noise was and still seems to be: * Independent of engine speed, IE the noise doesnt cycle faster as engine speed increases * Only happening under light-moderate accelleration * Sound makes a bell curve: - IE: 1K - 1.5 K You cant hear it 2K - 3K Becomes noticable 3K - 3.5 K Becomes very obnoxious 4 K -> 6K goes away completely I kind of figured my injectors were dirty cause they are 44K miles old, and when I pulled them out they looked like crap, and that was what caused the noise. Actually it got much louder and meaner sounding with the new injectors. I thought I had it figured out earlier today when I noticed my radiator was bone dry, and the noise was the water pump trying to pull fluid out of a nearly empty radiator. I filled it up and the damn noise is still there. Does anybody know what this noise is?

![]() It gets louder, to a point, with rpm, but it doesn't get faster with rpm, is this correct? What about while driving/in gear vs. parked/in neutral? If the sound can be recreated while parked, you need an assistant to throttle it while you listen around with a 3 foot piece of heater hose, and try to locate the vicinity better.
