car starts fine and when running normally around 3500 rpm the engine goes back to idle fine , but if taking it above 4000 rpm the engine then starts to idle at around 1600 rpm. as soon as i turn the engine off then back on again it sorts its self out and idles fine !!! any theories...cheers

yes sounds like the road speed sensor on the speedo cable. make sure its earthed properly.
