Why Does A Car Spit Fire From The Exhausts?

So to know how to make flames come out of your exhaust, you have to understand the working principle of it, why this wonderful phenomenon occurs. As you wonder, here is the working principle. The internal combustion engines burn a combination of oxygen and gasoline which come from the different sources. The throttle then will control the amount of oxygen that gets allowed into the engine’s cylinders and the engine responds by releasing the right amount of gasoline for proper combustion. 

When the engine is operating at full capacity, very large quantities of gasoline are dumped into the cylinders at partial throttle and this is the fuel for excellent exhaust flames. But if you suddenly take your foot off the gas quickly as possible, it will shut off the supply of oxygen while the fuel system is slower to react. Because the fuel in the cylinder does not have enough oxygen for the full burn, the fuel passes into the hot exhaust system and ignites. Therefore, the exhausts will spit fire.

The heat of the exhaust can light the fuel resulting in flames. recommend you to bring your car to a professional who will help to do ECU remap for you.
