Hard sharp left hand turn in my wagon means I loose fuel. Sucks on race tracks, on normal roads it doesn't happen that often to be often - You have to *really* be pushing it - And I like my front right tyres to last more than 2,000km.

This is obviously fuel slooshing away from pick up in tank. But, it comes back once the fuel gets back and the pump build pressure up. Your case is extra-ordinary. Try running some new wires!
