I had the same problem on an Oldsmobile, which is the same 3800 engine. Does it die when youre off the gas coming to a stop? In mine the Idle Air Control sensor was dirty, so the car computer wasnt getting a right reading on the air intake into the eingine so it thought that it was lower than it actually was. in responce the engine adjusts the fluel flow accordingly and there isn't enough to keep the engine going so it stopped. clean the valve or replace it
All SS Chevy Impalas' had the LT1.
Every 10,000 miles
every 10,000 miles
Probably every 5000 miles. Or 6 months.
You should probably change a Chevy Impala transmission fluid every 3000 miles. This also applies to most vehicles on the road today. It is also important to check your transmission fluid at least twice a month.

Goodwrench says to "Inspect" at 60,000 miles. I recommend at every oil change. Replace if cracked or damaged...
it shoulb be replaced about every 35,000 miles but some might be rivited into the value cover
you need a OBD-2 scan tool to clear codes
every engine needs fuel, air, and spark. which is it not getting?
Change it every 3500 miles if it is a pre 1995 vehicle. If it is a post 1995 Impala change it every 5,000 miles. It will say in your owner's manual. If you don't have one, you can go to a parts store and find a maintenance schedule on the first few pages of the Haynes manual for that vehicle.
Turn the ignition key to the on/acc position without the engine running. Press the accelerator 3 times within 5 seconds. Turn the key to the off position and then fire up the engine. The oil message should be gone. this is supposed to be done every time the oil has been changed.
