Why is my sportsman EFI spitting hot gas?
Later I did some reading on this and other forums and found several possibilities that could cause the same symptoms: Temperature-Barometric Pressure sensor wiring broken, the sensor itself is bad, the Throttle Position Sensor is bad, its wiring broken, the fuel pump going bad, and hot gas in the tank.

Why does my car sputter when I Turn on the engine?
The fuel filter ‘s job is to filter the fuel going to the fuel injectors and then enter the engine. A clogged fuel filter can cause the engine to get too low fuel pressure or cause a clogged fuel injector. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.
How did I Fix my Polaris Sportsman EFI spitting?
I removed and cleaned the T-BAP sensor, fuel tank, fuel lines, fuel rail, and the throttle body. l also replaced the fuel filter and burned a whole tank of fuel treated with Sea Foam. Finally, when I put it back together I double checked all of the connections/clamps from the air box to the intake manifold. None of that fixed the problems.

What causes a boat to sputter and lose power?
Everything from fouled or corroded spark plug wires to debris in the gas can cause sputtering or loss of power. The first step is to identify what the cause of the problem is. The easiest way to do this is by eliminating the simplest explanation first and working your way outward until you locate the issue. The most obvious answer is fuel.
