I have1990 Chevy Astro van,it starts just fine,when it warms up,driving it or sitting still in drive or reverse, it stalls,I start it back up,in park or neutral,it stays idiling.Idles cold,stalls warm

Check the ECM grounds, they are under the passenger side kick panel. When the engine goes to warm status, the Oxygen sensors come on, If there is no ground on the ECM then it starts pulling ground voltage across the sensors and that causes big issues.

My 1997 Chevy c1500 5.0L misses very bad with loud poping noise coming from underneath truck. This happens only after I drive for about 30 min. And turn off truck and restart. After I start it back up it...

Test that the temperature sending unit in the water system is working properly. When the engine is cold, the computer puts it in cold start mode. Once warmed the temp sensor tells the computer to stop sending excess fuel to the engine and taking the cold start mode to off position. If the sensor is faulty, it stays in cold start mode and keeps dumping excess fuel into the engine causing your situation. Like your running with the choke on after warm-up.

My chevy tahoe takes to long to heat up

To check if the thermostat is bad, start a cold engine, and feel both of the radiator hoses.
While they should both start cold, only one should heat up slowly. The other should stay cold.
Then after the warming one gets hot, only then should the other hose also suddenly get hot.
If both slowly get warm, then the thermostat needs to be replaced.
(By the way, make sure the coolant is full.)

I have 95 Chevy Lumina. March 2010 I had water pump, head gaskets, intake gaskets, thermostat replaced. Unfortunately I am having same problems as I did before all these parts were replaced. How can this...

Was the car over heating before the water pump and head gaskets were replaced? Putting in a new Radiator will make it run even colder.and take even way longer than the one hour it is already taking to warm up.The computer in the car commands the engine cooling fan On/Of at a predetermined temperature.It receives this data from monitoring engine sensors such as the engine coolant temperature sensor.So if it is defective and the computer is not recognising the defect it thinks that the engine is running hot when it is realy running cold and will command that the cooling fan be on.Resulting in the fan running in 24-7 as you put it. If you want the engine to warm up faster and the cooling fan to operate normaly then I would replace the engine coolant temperature sensor and the relay for the fan circuit as well. If you need to talk to me further about this you can use the reply box below. Please let me know how this goes for you and I hope this is usefull for you. Good Luck and have a good XMASS.

'96 Beretta has no heat. Coolant level okay. Fan

when you start the car and let it warm up, does it reach normal operating temp.? Does the needle stay in the middle? If not, it's time to replace the thermostat. If it's ok, then your blend door is stuck or broken and may need replacement or repair. when you move the control to hot or cold, the blend door opens accordingly allowing cold hor hot air in.
