Hey guys I know that if I put a vacuum gauge in the manifold I can measure the vacuum at idle and at WOT. What should the vacuum be at WOT? I know it's relatively low, but it can't be ZERO, or no air would flow into the engine. The reason I ask is that if the vacuum is still high at WOT, then I KNOW that my air filter is restricting flow into the engine.
Right?
Right?
