这几天下雨后,老车在红灯或停牌待速时,发动机转速表指针上下摆动,同时车身也震动.等开起来就没有这个问题(两月前因待速低曾调高过待速,但好象待速又降回老样子)不知道造成的原因是不是油路毛病?
>> Not 油路毛病?
今天雨天连开两个小时后, 现象变为在红灯或停牌待速时,发动机转速表指针剧烈上下摆动,同时车身也剧烈震动,然后车子熄火. 再打火后只好一脚踩刹车,另一脚踩油门,当转速表到1500后抖动消失,但松刹车起车时转速表指针又剧烈上下摆动,同时车身也剧烈震动. 速度起来后抖动现象消失.
>> Bad idle. Check distributor cap, rod(all should be clean), spark plug(not oiled or burnt.) and wire-set(resist should be between 5K~20K). coil-pack (should have good ground).
You should go to garage if you cannot do about check. Tell garage you need a tune-up specific or bad-idle on wet weather.
大侠们帮分析分析原因. 是油路毛病? Fuel filter两年多一直未换过.
>>Again, not.
另外一个毛病是高速公路开十分钟后,车身震动的烈害. 估计是轮胎的balance有问题,不知道是四个轮胎一起做BALANCE还是只需做两个前胎的balance?
Not because balance, if so, it should vibrate as soon as it reaches the speed. You should ask garage to have a road test or one guy here do test for you.(carman, looking_new, kapagi?) |
