【大纪元2019年04月05日讯】读者Maple问：Dear Mr. Lee, Yesterday morning, I tried to start my 2008 Volvo but with some problem. I needed to put in the key and turned it 6 or 7 times before I could get the car to run. The car mileage is 16,170. Usually I use the car about 4 to 5 times per month for shopping and appointment. Last week I had the same problem. But after seven times in turning the key, I was able to use the car. I made several stops to do errands. Each time I had no problem starting the car until yesterday morning. Do you know what the problem might be? Please email to me. Thank you for your assistance.
译文：亲爱的李先生，昨天早上，我试图启动我的2008 Volvo汽车，但是有一些问题。我需要插入钥匙，然后转动6到7次才能让车开动。汽车里程已有16,170，通常我每月使用汽车约4至5次去购物和约会。上周我遇到了同样的问题，但是在转动钥匙七次后，我才能启动它。在发生事故前，我已开它到多个地方办事，每次都没有问题，直到昨天早上开车。您知道问题可能是什么吗？请发邮件给我。谢谢您的帮助。
李进答：Hi Maple,
When you have to turn the key 6-7 times before you can start the car, then trouble shoot this way:
1) If engine starter did not crank until the 7th time, you may have a bad starter, or bad starter relay.
2) If engine starter cranks every time, but engine only started on the 7th crank, then you may have a bad idle control valve that requires cleaning.
3) You may also need to check the fuel pump.
译文：如果你必须在启动汽车之前将钥匙转动6-7次，那么请按照这种方式进行故障排除：
1）如果发动机起动器直到第7次没有起动，则可能是起动器不良或起动继电器不良。
2）如果发动机起动器每次起动，但发动机仅在第7个起动器上起动，则可能需要清洁怠速控制阀。
3）可能还需要检查燃油泵。
读者Peili问：你好李进，我有一辆2005 Mazda MPV。里程数55,000。有时在驾驶中或换档时车子会轻微抖动1-2秒。引擎灯亮过一、两天，后来又灭了。但问题还在。你认为怎么回事呢？
李进答：Peili您好。当车子抖动1-2秒，引擎灯亮，表示引擎燃烧出了点问题（燃烧不完全）。可以请修车师傅看看可否取读“故障码”（OBD-II error code）。引擎控制电脑会告诉是否有某些故障/状况造成这个问题。
如果没有故障码，可以看看是否是PCV管道堵塞，或清洁一下MAF传感器，或者某一个高压点火线圈（Ignition Coil）出了问题。
