Right from the FAQ section.


My engine cuts out when turning, but there is plenty of gas... whats wrong?
Fuel tank sock is dirty and needs to be cleaned or replaced, and or the baffles in the fuel tank are rusted away.

I had exactly the same issue on my TII. As it turned out, the hard left turn caused the main wiring harness to short out against the right front inner fender well. On mine, the harness runs directly between the turbo downpipe and the fender in the most narrow area and had cracked the insulation due to heat from the exhaust. Check the harness in the area of the exhaust manifold for any bare wires or signs of brittle insulation due to heat. Although it is NA, it will still produce ungodly amounts of heat and the wires are not protected very well. After rewiring and rewrapping about 6 wires in that section of the harness and then wrapping the whole thing in heat wrap, it seems to have eliminated the issue. Even if it isn't the issue, it never hurts to check the harness anyway to avoid a problem down the road.

thanks man. The Fuel sock is only 20 bucks at kragens and im sure it needs it regardless of if it fixes the issue. Hopefully it does and if it doesn't i will deff look into rewraping the wires by the exhaust,

Also happens when the tank is low. Hopefully you have more than 1 gallon in the tank and arent basing fixing anything off not having any fuel
