A Crown 3.0 has insufficient power and slow response to sudden acceleration. The idle acceleration can reach 4000 rpm, and the road test speed is only 2700 rpm, so the speed can't go up!

It depends on whether your crown is old or new. If it is new, the problem is not big, and generally this problem will not occur. According to my personal judgment of the car, you are the old crown, 90 years, 133 or 155. Those batches of Crown engines are all imported, so it is no problem to drive hundreds of thousands of kilometers. Now there are many such old cars in southern cities such as Dongguan, Guangdong. I suggest you clean up the idle motor and throttle, and change the machine filter and air filter by the way, and change some better engine oil, such as Shell, Castrol Magnetron, Mobil 1 engine oil. The above maintenance will not cost too much. After the change, you will feel that the car is quieter and more energetic than before. By the way, I am also a big fan of Crown!
