Welcome to the forum
Sounds like the EGR tube may be clogged. Try this, with the engine idling, apply vacuum to the egr valve, if the engine stumbles or dies, then it is working. If the idle doesn't change, then the tube or port in the intake is probably clogged.

check the vacuum harnesses near the battery. If battery acid spills over onto them, it will cause this condition.(ssm 10787) oh yeah, you have an outstanding recall on your cruise control.
