Speed sensor and fuel system problem??? My 02 Z is showing all the signs of a bad speed sensor (no codes). It has erratic speedo, loss of power under heavy acceleration, rough idle, etc.! Since a bad speed sensor will send "bad" signals to the fuel system... is it possible for it to throw a p0230 code (fuel pump primary circuit malf.)? The fuel pressure is at 61... which is fine. I'm confused!
