1981 Buick Skylark tech4 mileage: 122,000. I’m working on this car for a friend. Every once in a great while when you are coming to a stop the car shuts off it starts right back up but it takes a few minutes before you can get it to run in gear. I took the air filter out while test-driving and it did it one time for me. It doesn't appear to have any vacuum leaks, I checked it with carburetor cleaner. Why does it do that?

Your car may be ready for a major tune-up including spark plugs, plug wires, distributor cap, rotor, fuel filter and air filter. Also, perform a fuel pump pressure test. Clean fuel injection system including throttle bore, idle speed control motor and passages. If problem still exists, scan computer for trouble codes.
