QUESTION: no its not resolved. could u send the answer u found please? egr works. it will idle up and down between 1000 and 2000 rpms and will shut off. when stopped i have to put in nuetral and keeps rpms high to keep it from shutting off. i have no idea what to do

Answer
Hi Ron,
Here is the first answer:

"That egr is a very likely cause of the failure to idle, stall when slowing down. The chances are it it sticking slightly ajar which leans out the mixture. There is a good chance you can free up its action and avoid having to replace it. You will notice a slot in the stem (or a ridge) and that with a screwdriver you can move the stem toward the round vacuum-operated top against spring-action which is trying to keep it closed. I would spray some WD-40 on the stem where it enters the body of the valve proper, then try moving the stem back and forth to free up the action. If you can do that such that the spring will drive the stem to a dead stop in the closed position then that should solve the problem. Then you should see the stem move on it own when you do the revev/return to idle with the gas pedal. This is almost a routine maintenance sort of issue with these egr valves, so keep it in mind when it returns later."

Did you do the above? Are you certain that the valve moves freely, and that the spring-action causes the valve to close to a dead stop? It may be that the valve will not close all the way due to a build-up of croud around the valve proper in which case removal and cleaning out the passageway may solve the problem.
Other than the egr, the only way to get another possible cause is via a fault code readout. Use the ignition key:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the odometer window to see if the mileage reading changes to show any 4-digit numbers preceded by a P. It may be a vacuum leak so check as many of the hoses that are attacthed to the intake manifold to see if any are cracked or loosely fitting. There is a diagram on the underside of the hood that shows all the hoses.  But a fault code would be helpful, as well as certainty that the egr is truly closed tight at idle.
