They claim that the fuel control valve plunger may wear unevenly and over time become stuck in the open position. They state different things can happen including stalling. My research found that it can cause stalling at high speeds or in heavy traffic and it may cause a loss of control over the vehicle. ARE THEY TRYING TO AVOID A RECALL.
