Problem indicates electronic component failure due to heat from current flow
run the fault codes to determine the area or sensor that has failed
could be a cam/crank position sensor , ignition control module , coil,even the ECM

SOURCE: 99 hyundai accent engine surges and dies at start when cold

There a lot of cuses for this but you need to scan the vehicule before to know what sensor is having troubles, if is too much expensive the scan in your city consider to buy one. I see in ebay a lot of types of OBD2 scanners for $25-30!

SOURCE: oil pressure high when engine cold. but fine when engine is warm

It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.

2002 Ford Mustang GT, CAR STARTS UP FINE WHEN COLD. Hard to start when warm No Check Engine lights come on.


Think about how the vehicle is acting. Starts fine when cold, hard to start when warm. In these computer operated systems, the computer runs everything. Starts fine when cold: the computer has the engine in cold start mode putting more fuel in till it warms up. Temperature sending unit in the manifold sends a message to the computer telling it to stop the cold start mode and it stops dumping excess fuel into the cylinders and it runs fine. IF, mind you, IF the temperature sending unit is faulty, it's not telling the computer to stop the cold start mode and is flooding the engine with fuel cause it's sill in cold start mode. This is my take away on your situation and the temp sending unit is something to check to be sure it's functional. Check it out. I hope this WAS the answer to your problem my friend. It's typical. Luck to'ya Bro.

Hard starting in cold weather, turns over but does not start easily. Starts fine in warmer weather


check if the car have the thermostat in the cooling system, because in cold weather the thermostat close the water flow in the cooling system (radiator, head of the motor) and the car gets temperature faster to warm the engine to operational temperature.

Car Surges then dies at a stop only in hot or warm weather


Think about what you just said. Only does this in times of higher temps out BUT never in winters cold. Doesn't that seem strange to you. Well I guess it does, huh. Anyway, know these systems helps. When engine is started, the temp sensor tells the computer it needs to place the engine to cold start mode. It does this and extra fuel is put into the cylinders to keep it running like a choke on the carbureted engines. But those you can turn the choke off or it does this automatically from the warmer engine. If in fact the temp sensor is not telling the computer it's warm enough to be taken out of cold start mode, it keeps dumping excessive fuel into the cylinders an flooding the engine causing it to surge and then die, because it's flooded. Therefore, the temperature sensor is faulty and needs replaced. Do that and drive on.

Hi my pulsar idles/drives allryt till it gets warm then when its warmed up it want idle at all and when you cruse it missis and compresor surges but put your foot up it and it goes fine


Please check your fueling system. While clod car need rich AFR, in contrary while engine hot , your car need lean AFR. This why your car is running bad while engine cold.

yes you hit the nail right on the head there,, its the tem sensor playing you up, its telling the car's computer its warm when its still cold and it cuts back the fule like pushing in the choke,,, this causes the engine to miss fire and lack power till its warm change the sensor

Cold starts ok warms up shakes and stalls


check engine coolant temperature when it gets warmer, or at operating temperature, and verify that the temperature gauge is showing warmed up to operating temperature. If the coolant temperature sensor tells the computer the engine is cold it will over fuel and miss and the engine will die. When cooled down it will run fine until it warms up. Also could be coil if it starts missing after warmed up.

When my chev 2000 sub is warm hard to start


I have a really good hunch that your problem is the spark plugs. As with this when your engine gets warmer the plugs get hotter and they start to lose power when you try to start your engine. I am not positive on this but I am really certain, but with this problem there can be a number of things happening.
