Hi Bob,
My Jeep shop manual, 1984 to 1996 shows an EGR valve. On the 4.0 six it
should be located on the side of the intake manifold with a gas tube to
the exhaust manifold below. If the car truly has an EGR valve, it should
show on the Fed. Emission control sticker somewhere under the hood. The
sticker mainly shows hose routing.
Maybe the valve has been removed?
I have attached a pic. It won't show on the list copy.
Regards,
Dave Russell
