What is the reason for the poor acceleration of Porsche cayenne engine?

It is recommended to clean the air intake, exhaust, throttle and throttle motor before installing the air filter. If the fuel filler door is empty, see if it is clear. If the fuel filler is weak, it is estimated that the gasoline filter element is blocked. If it is not smooth, replace the filter element and clean the fuel nozzle. If the exhaust is thorough, especially for the three-way catalytic converter, if the exhaust is not smooth, it will lead to a great loss of starting power. I hope I can help you. .
