  • 枫下家园 / 爱车一族 / 请教各位DX,以前在 highway 上以 110KM/HOUR 左右的速度行驶时,发动机转速一般都是在 2500 RPM,可是从昨天起同样速度变成了2000 RPM,没有其他异常现象。不知道是不是故障的前兆?
    • 好事阿,engine is more powerful ... am I right?
      • I was thinking like you too... It should be a good news... anywayz, wait for egg sees this.
        • change to neutral and wait.....................
          • turn on the radio. It will take a while.
            • : ) I like Easy Rock 97.3
      • thansk, 可是我开的是辆比较老旧的车,不应该突然出现这种情况啊。觉得似乎说不太通。发动机突然变化,担心会出大毛病。
        • 回光返照?呵呵,对不起说这么吓人的话,神会保你平安的:-)
          • 嘿嘿,多谢祝福。
    • I think it is about the Crankshaft/Crankshaft Sensor; or your PCM is wrong, which is less possible.
      • crankshaft?! 这么严重?还有就是现在加速比以前慢了。猛踩油门发动机转速也达不到 4000 RPM
        • Actually I am not sure. i think the PCM calculates the RPM according to the CKP sensor's input, so if the RPM is not correct, it might be the sensor's problem, esp the car is old.
          • 哦,多谢!!! 这个东西如果修理会不会很贵?
            • I am really sorry I have no idea.
              • Anyway, thanks for your posts... :- )
    • 非常严重的问题,建议清洗化油气。
      • 用过那种瓶装的 Fuel Treatment & Injector Cleaner, 似乎不见什么成效。: (
    • 這裡有搞汽車修理的嗎﹖
    • 可能性挺多的,最好的是GAS FILTER该换了,去查一下吧,其他的可能都比这贵,象火花塞或线出问题,甚至ENGINE的SENSOR,EMISSION SYSTEM都可能,找DEALER或大的地方详细查一下会比较好
