Question about 1992 Cadillac DeVille
Even though this is an old post i feel it needs an answer since there is 225 followers wanting an answer. This situation sounds as if this vehicle is either suffering from the Throttle Position Sensor switch which has bad spots in it causing lack of voltage or the Fuel rail pressure regulator which can not keep the fuel pressure built up in the fuel rail making the auto veel like it is running out of fuel.And the transmission speed densor which also controls fuel. The situations for each device has a test that can be done to determine which one it is. And last but not least lets never forget our fuel filter this can cause the exact same problem. I am eliminating the cam sensor because it stabilizes at idle. Eliminating the crank sensor because it too at idle also stabilizes and returns a smooth idle. So a fueling problem is what we have here one of the above. Enjoy and if you need help determining which one just ask me I will help you figure it out. Please rate my advise thanks it is how i receive my achievements.

Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving
