我解决了怠速低的问题
车辆:老VAN,170000公里 故障:怠速低,踩刹车等红灯的时候为500多一点,正常应该在700到800之间 解决办法: 1 使用NAPA 买的 CRC Throttle body cleaner,部件号:75078。 和这个相似,但图中是07078。我不是说图中的这个不能用,我原来想买这个,可是没有。 2 首先将进气管卸开。看一看图,是不是很好打开。不过那个管子有弹力,可能有点碍事。 3 打开进气管之后,往发动机方向看,应该像图中那样。按照罐子上面的说明,应该用整罐,我用了大半罐,没有全用完。 效果: 问题解决了,踩煞车的时候800左右,挂停车档的时候接近1000。 注意: 1 操作之前,要将电池负极拔掉 2 第一次打车可能有点费劲 3 这只是本人的经验,可以模仿,效果自负。 |

http://minimopar.knizefamily.net/idleproblems.html Vacuum Leak The first thing to check for here is a vacuum leak. Sometimes it can be difficult to track down broken hoses, but it takes a large vacuum leak to cause a high idle. Check the rubber hoses that connect directly to the intake manifold and throttle body. These are the most likely to fail. The best way to track down a mysterious leak is to remove a vacuum line and block its source with your finger. If the idle speed drops significantly below where it was before you removed the line, then you may have found your problem. Also look at the gaskets and air ducts between the throttle body and the intake manifold. It is unlikely, but you could have a leaking intake manifold gasket as well. |
