This code is usually caused by a loose gas cap or leaking gas cap cent diaphragm, the purge valve is under the car near the fuel tank

had same problem i would check the Idel Air Valve and also check all of your vaccum hose lines makeing sure there are no cracks or splits in rubber connectors if there is repair immediatelt because over time they start to dammage the internal parts fo the engine and if youve replace tps mass air etc. sounds like a vaccum hose problem

The EGR Valve on this 3.8 L engine should be in front of the throttle body on the drivers side of the engine just to the right of the front valve cover. If you locate where the intake tube/duct attaches to the throttle body and then move just a few inches toward the front of the car it should sit right in that spot. It will have two bolts attaching it to the intake/tube. Hope you find it!!

The EGR, or exhaust gas recirculation valve, takes inert exhaust gasses drawn from the exhaust system and reintroduces them into the combustion chamber through the intake manifold. This process lowers the peak combustion temperature and helps combat the formation of Nitrous Oxide (NOx) in the exhaust.

1. Separate the intake ducts from the air cleaner assembly by loosening the retaining clamps and pulling the ducts away from the housing.
   
2. Disconnect the vacuum line from the air cleaner assembly.
   
3. Remove the wing nut that secures the air cleaner housing lid to the base.
   
4. Remove both the air cleaner hosing lid and base.
   
5. Locate the EGR valve. Look at the front of intake manifold. The EGR valve will be bolted to the intake manifold just in front of the carburetor.

I also have a 92 Lesabre. I couldn't find the EGR valve either, so I asked the dealer where it is. They looked up the part and were surprised to discover the 92 Buick Lesabre did not come with an EGR valve. It's hard to believe, but you can verify it by calling the dealer and asking them to look up the part. It doesn't exist. Apparently, the 92 was the only year the Lesabre was manufactured with no EGR valve.
