Hi there. From the description you have provided, your vehicle’s drivability concern should be diagnosed and repaired. It is not advisable to drive your vehicle with the MAP (manifold absolute pressure) sensor disconnected. The MAP sensor’s job is to determine the load being placed on the engine and deliver fuel to the engine accordingly. With the MAP sensor disconnected, the fuel delivery will be excessive and could cause harm to the engine and exhaust system (catalytic converters). Your vehicle getting on the freeway accelerating, bogging down, and reaccelerating sounds like fuel starvation. It could be a fuel pump fault or a plugged fuel filter. I recommend having your vehicle’s drivability concern diagnosed and repaired by a certified technician, such as one from YourMechanic.
