i was just on my way home from work and pulled up at a stop sign and every thing was ok. i moved foward a little to make sure no cars were coming and tried to stop(going about 5 mph) and the brake pedal would hardly budge (compared to power braking) the car will stop but you have to push really hard on the pedal and it stops slow. no long after my check engine light came on and i could hear a terrible screeching noise from around the area of the inlet plenum and s/c outlet. i guess its a long shot but does anyone know what this could possibly be? any suggestions greatly appreciated. if i cant figure it out im gonna have to take it to Ford.
