EGR Valve test

[talonkev]

Does anyone know if the egr valve ports should leak vacuum? Im having an idle problem and i think it could be the egr valve. When I apply vacuum to one port it holds it, but when I apply vacuum to the other port it leaks out somewhere. Is this how the egr valve should act. I have tried 2 different egr's and they both did the same thing? Any help would be greatly appriciated.

Get rid of it. install a block off plate. Easy fix

I should block it off so I increase partial throttle knock and lower my gas milage while having no positive affects?

Actually, increased horsepower and better fuel consumption would be your positives... your EGR actually makes the air coming into your car "dirty" with exhaust fumes, making it burn worse... So you'd get a better fuel burn consumption and an increase in horsepower because clean air burns WAY better than dirty air.

Wasting gas is not a positive effect, the exhaust is not "dirty" it just leaves some carbon residue in the intake manifold. That little bit of carbon is not enough to effect the flow of the intake manifold. At partial throttle the egr allows the fuel mixture to burn more efficiently. At WOT the egr valve closes and the exhaust is not allowed back into the intake track. At any rate, does anyone know how the egr valve should react when vacuum is applied?
