1994 Buick Regal GS 3.8L stalling at idol

My 1994 Buick Regal GS 3.8L is stalling at idol. Whenever the car is not accelerating it hovers at about 1000 rpm which i would figure is normal. However the car rpm's will suddenly drop to almost 0 and then die. On occasion it will bounce back up and the car will continue to run. This occurs at any speed whether driving at 60 or slowing down to stop. I watch the rpm's and as soon as i take my foot of the gas it either dies or the rpm's drp to almost 0 then back up to 1000 rpm's

Looks like the nozzles have got some deposition on it. Spray some carb cleaner at the fuel intake wiht the engine running. If the sound becomes slighty better/healthy then add some more carb cleaner to the fuel from the fuel filter and start the engine and rev up & down to clear nozzles thoroughly................sodeep

When my 94 Regal GS frequently wouldn't start for 30 minutes to an hour after being driven, it was the crankshaft positioning sensor that needed to be replaced. I also replaced the harmonic balance pulley. The car ran more smoothly and started everytime.
