1. ABS在你踩刹车时会开始DETECT THE WHEEL, 如果4个轮有某一个SENSOR(或线路)不正常, ABS灯会亮.
2. some parts need to clean. (or it's about spark plugs)
3. idle speed is rough. there would be some problems. Did you change spark plugs when the car was at 100000KM? the air filter need to be changed. Maybe it needs some turn-up work.
Don't worry, Ford car is very good. Your small problems are very easy to be solved with small money.
