Question about Jeep Grand Cherokee
If no one has removed the EGR valve and inspected and cleaned it that could very well be your problem. If a pice of debris, ( chunk of carbon) has become lodged in the EGR valve that will definately cause rough idle and stalling. There are 2 bolts that mount the EGR valve to the intake manifold. center rear ov the intake manifold. You will have to disconnect 1 elecrtical plug on the EET ( Electronic EGR Transducer) to get it out and the EET has 1 vacuume supply hose to disconnect also. takes about one half hour to pull it off and reinstall it. When you take it off, you need to inspect the mounting surface and 2 exhaust gas ports. if a large build up is present you need to clean really good. a wire bore brush and carb cleaner works well for me. make sure the valve moves and seats fully. if you can apply vacuume to the top port and make sure the valve opens and closes when vacuume is released. If it does not, or you have a vacuume leak in the EGR valve you would need to replace it. they run about $80.00 to $100.00 at your local autoparts store. Also replace the EGR gasket when and if you reinstall the old EGR valve. a new valve typically comes with a new gasket.
