Re: Pulse air tube
Removing the pulse air is very simple. Disconnect the two thin vacuum lines that run from the pulse air to the vacuum junction block on top of the valve cover. Plug the open holes in the junction block with screws or golf tee's. Unscrew the hose clamps at the tops of the metal pulse air tubes and remove the valves. One metal line goes to the catalytic converter and the other goes to the exhaust manifold down pipe. You can either cap these off where they are or you can cut them back to within a few inches of where they start and close them off their. To close them off, just use vise grips to flatten the metal tubes and then fold them over them selves a couple of times. Just make sure it won't affect any emissions tests you may have where you live.
