ENGINE STALLS OR STOPS

1993 Saturn SL2

Engine Performance problem
1993 Saturn SL2 4 cyl Front Wheel Drive Manual 200000 miles

My car stalls or wants to shut off when I am coming to a stop. So, I have changed the fuel filter and added injector fluid and gas treatment to a full tank of gas. It ran normal for about 7-10 days, then it started with the stalling again when coming to a stop. When it doesn't stall, it drops well below 1 RPM as if it wants to shut off. What's going on?

U have any engine codes?U could have a bad coolant temp sensor or carboned up valves causing them to stick open when comming to a stop to check that have ur car in park idling then hold the rpms up to 3000 rpms 30 secs then drop ur foot off the gas fast let it idle down if it stumbles then smooths out u probably have sticky valves do this atleast 4 times. Let me know what u find.
