    car runs fine but every so often it will cut out like it is not getting gas. If i feather the pedal it will not stall but if you let off the pedal it will stall. Lasts anywhere from three min. to twenty seconds. It will also rev eratically sometimes in park while idling.

1988 buick regal stalls and restarts stalls and restarts


Sounds like a relay or coil failing.
To proceed you would need to find out if you are loosing spark to the plugs or fuel pressure to the injectors when it won't start.

Replace the fuel filter. If that doesnt do it which it probably will, make sure the fuel pressure is consistent, as it could be a faulty fuel pressure sensor.

1995 Buick LeSabre - Stalls then restarts while driving


Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.

Low idle


Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk 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 cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Possible solution to stalling '99 Buick. My '99 Buick Century would die for no apparant reason with no error codes. After 4 days at a Buick dealership and many frustrated mechanics, the problem was corrosion from under the battery location. The wiring harness had small amounts of corrosion internally. Check the wiring under the battery for any corrosion. This has been the problem on more than 1 vehicle that we are aware of. No service bulletin has been issued by Buick.

There are 3 things that cause this, 1st and most common is a dirty idle speed control valve, 2nd is carbon on the back of the intake valves, last but not least is the wrong octane of fuel, if it requires 89 Octane and 91 or 92 is used the engine will stall code.

To clean the dirty idle control valve follow this procedure:
