Greetings, I have a 1986 crown victoria that I have been restoring. I have recently had upper engine gaskets replaced new plugs, wires, cap and rotar. Since having this work done my check engine light comes on when I bring the car to a stop while idelling. When I continue to drive the light goes off.I have also noticed a sound coming from the engine like a spring or diaphram trying to close for about 10 seconds then it disappears.I'm wondering if this could be my EGR valve.
Any suggestions would be helpful. Thanks, Mac

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.

Yes, the EGr could be at fault. It could also be a faulty Manifold air charge temp sensor (slower moving air is usually hotter). It may also be an oil pressure sending unit, since the oil pressure decreases when the engine speed decreases.
