The check engine light was on, and the vehicle was in limp mode. The customer also reported that the vehicle was hard to start and regularly stalled.

Confirmed the vehicle was hard to start and had a history of stalling. A scan of the engine system identified fault code P0108 - Manifold absolute pressure (MAP) sensor/barometric pressure (BARO) sensor high input. Freeze frame data was checked, and the fault code was cleared. At that stage, the vehicle did not immediately fault again and drove normally on the initial road test. The MAP sensor was removed for inspection and appeared clean, with no obvious terminal tension issues. The vehicle returned two weeks later with the same complaint.
