2003 Chevy impala. engine stalling after it's warm or idling. Also will sputter a lot and not start up again for hours

SOURCE: Engine sputters as the car accelerates before it

Check your MAF Sensor on your air intake you may need to replace this sensor some are cheap you can go to Auto Zone or any auto parts store to order this or take it to a mechanic and have them diagnose this problem.
Or check your air intake hoses etc if they are loose or just a little your engine will hesitate or run too lean and the engine light may go on.

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.

Engine is difficult to start when cold

1. Check the battery condition, battery state of charge and starter motor current draw. Replace the battery if marginal and the starter motor if the current draw is beyond specification.
2. Check the battery cable condition. Clean the battery terminals and replace corroded or damaged cables.
3. Check the fuel system for proper operation. A fuel pump with insufficient fuel pressure or clogged injectors should be replaced.
4. Check the engine's tune-up status. Note the tune-up specifications and check for items such as severely worn spark plugs; adjust or replace as needed. On vehicles with manually adjusted valve clearances, check for tight valves and adjust to specification.
5. Check for a failed coolant temperature sensor, and replace if out of specification.
6. heck the operation of the engine management systems for fuel and ignition; repair or replace failed components as necessary.

1. Check the air filter and air intake system. Replace the air filter if it is dirty or contaminated. Check the fresh air intake system for restrictions or blockage.
2. Check for loose or deteriorated engine grounds and clean, tighten or replace as needed.
3. Check for needed maintenance. Inspect tune-up and service related items such as spark plugs and engine oil condition, and check the operation of the engine fuel and ignition management system.
