Just an update, we didn't want to take the time in removing the fuel system so we held it to the side and unscrewed the 8 bolts holding the intake in, after that it was pretty simple to detach the intake manifold and "finagle" it out. However, i did run into a problem with the chosen header going in to replace the old exhaust manifold and had to grind the outsides of the intake manifold around the bolt holes in order to make the exhaust manifold fit correctly.

The map sensor on a 1988 Buick Century is typically located on the intake manifold or near the throttle body. It is a small, electronic device that monitors the intake manifold's pressure to help regulate the engine's air-fuel mixture. To access it, you may need to remove the air intake duct or other components for better visibility. Always consult a repair manual for specific details related to your vehicle's configuration.
