Ford Thunderbird SC Problem Report
Ford Thunderbird SC Engine Stalling and/or Hesitation on Acceleration due to Faulty Idle Air Bypass Valve
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
Same problem here. Trouble starting, stalling out when idle directly after starting, and hesitation when accelerating. Replacing the idle air bypass valve fixed it all. - Visitor
