The Chevy 4.3 egr system is important to the proper operation of the engine. A clogged egr can cause rough idle or low fuel economy, among other things.
It should be on the front of the intake manifold directly above and behind the water pump.
the vortec 4200 doesnt have an EGR system
The EGR valve on your Astrovan is on the backside of the intake manifold just under the throttle body attached by two bolts. After installing a new gasket be sure and torque the BOLTS to 17-18ft lbs or the NUTS (if yours has studs) to 15ft lbs)
I have the same problem with my truck, It notorious... You have a stuck EGR valve.. Replace the EGR valve and it should work fine.
