This gold looking gizmo at the bottom right is an EGR valve. Sometimes with age and use, and considering this CJ8 is 28 years old, grime and gunk get in the EGR valve which causes the diaphram stick and not open and close like it should. I took the EGR valve off, and placed it in a container filled with carb cleaner. Carb cleaner can be your best friend! After soaking the EGR valve for an hour, I pushed on the diaphram a few times and no more sticking! I bolted back on Jeep and re-connected the hose. Not sure if this helped anything, but I now know it works!
