Default 93 oldsmobile 88 egr issue ...i think

Got a 93 oldsmobile 88 two months ago, replaced batt, alt, starter, plugs, wires, and fuel filter.

Now im having an issue that when i stop at a light or stop sign the car stalls out and shuts off i have to put it in park and start it back at. I was told to change/clean the egr valve and the ports.

Where are the ports located on the 93 oldsmobile 88 with a 3800 egine?

I had a similar problem with my 94 Park Avenue. It was the TPS sensor.
