There are a lot reasons. The simplest one is spark plug wires and maybe sparks itself. In more complicated cases it might be the computer, one of sensors and so on.
The difference in temperature between a warm tube misfire and a warm tube misfire in hot weather is the temperature that resulted in the hot weather .
It starts better when its warm!
Misfire is usually caused by faulty spark plug wires or spark plugs or both. I don't see the throttle body causing misfire.
Thermostat
there is no explanation it just keeps them warm sciencetist dont know fully about their feathers that is made to keep them warm.
Check your ignition module. When it gets warm or hot it loses spark if its faulty.
most cars misfire when it is really cold. try to warm up your engine before starting it up. If it still misfires when it's a nice day, something is wrong with your engine (spark plugs, battery, etc.)
My car is a 1997 Mitsubishi Galant, and when it was idle it used to do the same thing, I was told it might be time to change the TPS Sensor (Throttle Position Sensor). I still need to change it, but what I figured out, is that when you let the car fully warm up, when the needle is as close to the middle as possible, it won't shake and turn off.
The LS is prone to coil failure which leads to a misfire in the affected cylinder. A misfire due to a failing coil usually happens when the engine is warm and under load (low RPMs, accelerating or going uphill). The misfire may feel like a transmission problem because it causes the car to buck and stutter as though the gears were skipping or getting stuck briefly. The worse the misfire gets, the harder it will be to accellerate. Sometimes the misfire condition can be overcome by applying more RPMs or reducing the load on the engine. See my post about the valve cover leaking issues contributing to this issue.
1996 Ford Contour is sometime caused by a misfire on startup. The error will clear itself after 3 complet warm-up cycles not restarts.
When fully warm 190-210F
To warm a fully cooked ham for optimal serving temperature, heat it in the oven at 325F for about 10-15 minutes per pound until it reaches an internal temperature of 140F.
