All the things suggested but before assuming that the plugs read okay do a
couple of hot shutdown's--that is, kill the ignition when at full
throttle--both when you are in that "stuck' range between 2500 and 3200 and
when you are at higher revs.  Perhaps a valve is hanging or one plug is
misfiring and then clears, but the plugs may point the way to the problem.
