冷车或水温未完全上来.转速1500至2000保持在一个点上,2档或3档,车子会一冲一冲的.还会嗡嗡响.转速过2000或水温完全上来后就不会了.之前4S检测多缸,查了油路电路最后说油品问题.可换了油还会.今天又上4S了,又测出多缸失火。4S搞不定,等厂家技术员过来检修。郁闷!4S跑4、5回了.同志们有同感的都上4S检测下.看是通病不?还有在水温上升过程发动机有:吱吱的异响.师傅说是喷油声？？？？？我不这么认为。貌似高压漏电打火声<img src="http://club1.autoimg.cn/album/userphotos/2013/11/11/500_aa29_f82ede4e_f82ede4e.jpg" style="font-size: 16px; color: red; width: 700px; height: 933px; "><a title="" href="" target="_blank" style="font-size: 16px; "></a>http://player.youku.com/player.php/sid/XNjMzMzk2NTYw/v.swf<a title="&lt;embed src=" http:="" player.youku.com="" player.php="" sid="" xnjmzmzk2ntyw="" v.swf"="" allowfullscreen="true" quality="high" width="480" height="400" align="middle" allowscriptaccess="always" type="application/x-shockwave-flash" style="font-size: 16px; color: red; ">" href="<embed src="http://player.youku.com/player.php/sid/XNjMzMzk2NTYw/v.swf" allowfullscreen="true" quality="high" width="480" height="400" align="middle" allowscriptaccess="always" type="application/x-shockwave-flash">" target=_blank&gt;<embed align="middle" src="http://player.youku.com/player.php/sid/XNjMzMzk2NTYw/v.swf" width="480" height="400" type="application/x-shockwave-flash" allowscriptaccess="always" quality="high" allowfullscreen="true"></a>
