I NEED TO REMOVE THE EGR VALVE
The Exhaust Gas Recirculation valve does just what the name implies: it
diverts some exhau st gases back into the intake system at low engine
speeds. This lowers combustion temperature to reduce NOx levels. It also
reduces throttle response and bottom-end power.
Disabling the EGR valve is easy. Locate the valve and the EGR vacuum
modulator valve (two gold-colored metal stampings, usually at the rear
of the engine). The EGR valve has steel lines leading to it from the
exhaust manifold. The EGR vacuum modulator has two vacuum lines between
it and the intake manifold and a third vacuum (soft) line between the
modulator and the EGR valve itself.
EGR Vacuum Modulator
EGR valve (arrow) is shown adjacent tosimilar EGR vacuum modulator
valve. EGR valve is connected to exhaust manifold with steel lines.
Modulator has vacuum lines only.
Disconnect the vacuum line between the valve and modulator and place any
solid object of appropriate size (dowel, etc.) in the line, then
reconnect the line. Or you can get a EGR block off plate
