我的老伙伴TOYOTO CAMERY最近越跑越慢了，夏天2100转（开O/D）跑高速能跑到100-110公里，现在同样转速只跑到80公里左右，请问是传送的问题吗？我的速度表也是要跑了一段时间以后才能显示正常速度，开始时指针不动。请问这两者有关系吗？谢谢

A V6?
Are you sure the tachmeter is correct? Did you feel sluggish when accelating? Does automatic transmission have delay or jerky?

里程表没问题，而且能感到加速时比较吃力。C建议我去清洗ENGINE还空气滤清器。现在换雪胎后2100转只跑70公里。晕啊！

Lots of gas and $$$?
In winter when ATF is very cold, the effectness of torque transfer before drive and slave torque converter inside automatic transmission is very low as well as torque from engine. That's why you feel like towing, in that way you feel engine is rev higher but speed is not catch up.
The snow tire, especially those tires for snow (not for ice) with big stud are also less effective on the road.
You should be better when car is warm, right? I guess you have an old automatic transmission car, which eats some of engine revolution on cold weather and snow tire. Even with manual transmission, it still eats some engine revolution.
Eating revolution in your car is too much. Does it do the same when car is hot?
