Why does my engine start and idle fine when cold and once warm it dies or when I accelerate it bogs down then dies?

Sounds like the engine is getting too much fuel. That may sound odd, but that is what happens during cold or first start. For example the old carburetor choke. The butter fly restricts air intake, which forces a richer fuel mixture. Fuel injection is computer controlled, so the computer allows more fuel to be injected. Is your car smoking black or dark gray? Is their a strong smell of gas after it stalls? Assuming your vehicle is carbureted. If so more than likely it is getting more fuel than is needed. If it is cdarburete the air fuel screws at the bottom of the carburetor need to be adjusted ( clock wise or turned to the right if I remember correctly) This should decrease the amount of fuel entering the jets. Your probably getting pretty bad mileage!

Yes the reason for that is because the engine is over heated and when its cold the engine is nice and cold perfect for starting conditions.
Why does a Car bogs down when cold?
In a cold engine, the fuel that is introduced to the air to create the fuel air mixture sometimes does not fully evaporate, resulting in incomplete combution, which in turn reduces power.

Why is it hard for a car to start when the engine is cold?
It is not so much hard for a car to start when the engine is cold as it is easier for a car to start when the engine is warm.Cars that are hard to start in the cold are usually not new cars any more and because of wear and tear there is more likely to be something that doesnt work as well. when fuel is warm it ignites more easily.
What is an engine cold start?
It's when you start the engine when it is either really cold out, or the car has been sitting in a temperature region for a while where it has not been run and exposed to cold conditions. This is where more than 50% of engine wear comes from, the cold start because the oil has thickened and therefore does not pump through to the most crucial parts of the engine as fast. best advice is to use the manufacturer recommend oil viscosity (ex: 5w30 or 5w20) thicker oil does not help. And the use of synthetic and synthetic blend oils does help to reduce engine wear at a cold start.
Why is your Hyundai elantra slow to accelerate when the engine is cold?
most likely reason for any vehicle to perform under its natural ability when cold is simple. cold engine= thick oil + more friction + less horsepower. until an engine has reached its optimum temperature and oil is warm and not thick anymore, there will be alot more friction inside the engine making it harder for the car to run.
