GG,

The ECM is getting a vacuum signal that is below operational for the secondaries to either open or stay open. Turn the ignition ON and see if the secondary vacuum pump is operating. If it contnues to run, then you have a vacuum leak likely under the plenum. You are limited to 3000rpm when secondaries throttle is not operating because ECM will not allow secondary injectors to turn ON.
