In 2.6$\pm$0.2 of $pp$ collisions at $s$$=$1.96 TeV recorded by the CDF II detector we observe no candidate events, consistent with a standard model background expectation of 1.4$\pm$0.4 events. We set limits on the cross section at the 95% C.L. and place the world's best limit of 149on the mass at $\tau_\chi_1^0$$<<$1 ns. We also exclude regions in the \none\ mass-lifetime plane for $\tau_\chi_1^0$$łesssim$2 ns.
