也许对你有帮助,就唠叨几句。

最近车的怠速不稳,在4001000之间打拍子。等红绿灯的时候总有一口气叨不上来,就歇菜的感觉。某天终于死了一回,所以抽空去CT想查一查。“检查Engine$80”。然后呢?“可能是throttle position sensor坏了,也可能是idle air control motor的问题。”这小子我跟他有点熟,前几天刚在这儿换完刹车,所以还能套几句话。心说没几百今天是别想开走,就敷衍了几句说考虑考虑吧。

回来后想起有一次一个插口松了,就宰了我几百刀的惨痛经历,决定先做点功课。Google了一下,这怠速不稳的原因还很多,那我就先从简单易行的,不用花冤枉钱的地方着手。我这车跑了八万多公里了还没换过火花塞,也到口了。去CT买来8个换上,车Smooth很多,可有时还会“抽风”。Air filter也从来没换过,以前也没当回事,去Dealer那儿买了个新的换上,试试,还是不灵。看样子不是正常保养的问题,心里少了份内疚,因为我对这种奢侈的保养一直不太感冒。接着上网搜,看样子也许还真是throttle position sensor idle air control valve的问题?有个哥们换了idle air control valve之后问题依旧,换了throttle position sensor后修好了。不过,花钱买件之前还有两项不用花大钱的事情可做,一是检漏,另一个是清洁throttle body。没发现有漏气的地方,就花$10CT买了瓶throttle body cleaner,从intake喷进去,嘿嘿,修好了。
 
Modern electronic fuel-injection systems are some of the most trouble-free systems in your vehicle. However, if your vehicle has accumulated more than 75,000 miles, there is some routine fuel-injection-system maintenance that should be considered. The two most common maintenance jobs are fuel-injector cleaning and throttle-body cleaning. Cleaning fuel injectors is generally not a do-it-yourself project, but you can clean the throttle body on your vehicle with common tools and specialized spray cleaners.
