Immediate Actions (while driving):
1. Try to free the pedal: Gently but firmly try to lift or wiggle the gas pedal. Avoid jerking it.
2. Shift to neutral: If you can safely do so, shift the vehicle into neutral. This will stop the engine from accelerating. Do this *only* if you can safely pull over.
3. Steer to a safe location: Gradually slow down using the brakes and steer to the side of the road, away from traffic.
4. Turn off the ignition: Once stopped and safely off the road, turn the ignition off.
After safely stopping:
* Do NOT attempt to drive the vehicle again until the problem is fixed.
* Inspect the pedal: Look under the dashboard to see if anything is obstructing the gas pedal's movement. This could be something as simple as a dropped object or something more serious like a broken cable or linkage.
* Call for roadside assistance or a tow truck: You'll need professional help to diagnose and repair the issue.
Possible Causes (requiring professional diagnosis and repair):
* Stuck accelerator cable: The cable connecting the pedal to the throttle body might be frayed, broken, or stuck.
* Throttle body issues: The throttle body itself might be malfunctioning.
* Vacuum leak: A leak in the vacuum system could cause the throttle to stick.
* Electronic throttle control (ETC) problem: If your Windstar has electronic throttle control, a sensor or the module itself could be faulty. This is less likely on a 1998 model, but still possible.
* Something lodged under the pedal: A simple fix, but needs to be investigated.
Important: Do not attempt to repair this yourself unless you have extensive automotive experience. Improper repair could lead to further damage or create a safety hazard. Have a qualified mechanic diagnose and repair the problem. The safety of yourself and others is paramount.
