My way of thinking, if one was driving the car and you went to WOT the vacuum gauge would show some psi if the exhaust was blocked.
No , always a vacuum on intake James, how could it go to pressure when valves are sucking in air and exhausting. Since exhaust is plugged it cannot continue to draw air in and gets less vacuum.My way of thinking, if one was driving the car and you went to WOT the vacuum gauge would show some psi if the exhaust was blocked.
If air cleaner was clogged that bad it would be severely flooding ,just like having choke fully closed.It would be blowing black smoke .What are you using for an air filter and how long has it been since it was changed?
