Engine idles fine on startup (i.e., starts high then immediately backs down to low idle), but after high throttle (i.e., normal skiing, etc.), idle does not come down below 1000-1100. I have looked at the linkages, and the idle easily comes down if I 'jiggle' the linkage. Is something sticking or is it something with the EFI?

This problem has got to be rough on the transmission shifting into fwd/reverse.

Thanks in advance.

try cleaning the carbon build up off the throttle body and butterfly plate, and applying lubricant to the cable and linkage.

You could also pull linkage off of butterfly plate and see if it is binding.
