最佳答案

汽车在冷启动时出现怠速不稳、加速无力的问题,由于没有见到现车,分析原因可能是因为节气门、怠速马达、进气道、进气门和燃烧室及喷油嘴等部位的积碳过多造成的。
您不仅要清洗喷油嘴和进气歧管,还要检查清洗节气门和燃烧室内部的积碳。因为在冷启动时,积碳会吸附一定的混合气,就会导致启动时混合气过稀,再加上近期气温很低,混合气雾化不好,从而造成不易启动;或者是因为碳罐或碳罐电磁阀出现问题,造成启动时混合气过浓,也会引起不易启动。
还要注意检查火花塞的工作情况。建议您根据以上分析的内容去4s店进行现场检查。更多相关信息请登录第一车网二手车百事通栏目：http://www.iautos.cn/news/newslist.asp?lm=20020009
