Check the engine oxygen sensor. It seems that the system is going into closed loop mode from open loop and the oxygen sensor may be bad. Here's the process:

Engine starts OK, O2 is open loop running on mapped data in the controller

Engine warms and switches over to closed loop, O2 sensor hasn't started putting out valid voltage levels yet so engine stalls.

After a few more minutes 02 sensor is hot enough and is able to supply valid, closed loop info to the controller. It's called a lazy sensor, this means it's worn out and due for replacement.

What is it when 99 infiniti g20 shuts off when putting it in reverse or making a stop but drives fine after car is warmed up for at least 10 minutes and is also worse when its cold out?

I have the same exact problem.


What makes a car blow blue smoke it stops after the car is warmed up the oil level is fine but the first start after sitting a while blows blue smoke for roughly 2-3 minutes?

I would suspect the valve seals are worn. When you shut the engine off, the oil that is on the valve stems, slowly seeps past the seals into the combustion chamber. At start-up this oil is burned away creating the blue smoke. The oil will not seep past the seal while the engine is running. It can be fixed without removing the head but unless it get excessive, I would just leave it alone. Just make sure to check your oil level regularly, as it will eventually need topping off.


Steam is coming from the left-hand side of the radiator when running fan does kick on and it stops Does my radiator have a leak?

It may NOT be a leaky radiator. However, you may wish to check your upper and lower radiator hoses and tighten all of the fittings (if necessary), and also trace the hoses all the way down to where they meet the engine. Be on the look-out for dry-rot and be looking for spots that might be bulging out. The bulging spots could indicate that the hose is ready to burst. It is best to conduct this inspection while the vehicle IS running and HAS BEEN running for a few minutes so that it is warmed up. BE SURE to be VERY careful because radiator hoses are HOT, and engine compartments are intentionally small. P.s: IF you can identify to the location and actually SEE the steam coming directly from your radiator, then yes, you DO have leak in your radiator.


Explain how radioactive decay has always warmed the earth from the inside and how nulear fusion has always warmed the earth from the outside?

The Earth's core contains many radioactive elements within its core that emit warmth as they decay, keeping the core of the Earth hot and heating it from within. Meanwhile, the sun is a product of the nuclear fusion of hydrogen into helium and its rays warm the Earth's crust from outside.
