RPM Very High

Hello! I changed the intake manifold gasket on a '96 Oldsmobile Cutlass Supreme and now after that the RPM at idle jumps to around 2500. But drives fine though. Any ideas why the RPM is so high now?

Not 100% sure, but there may be a vacuum leak somewhere. I had a '87 truck that did the same thing and it was a vacuum leak. Thanks, Steven
