Wang Wei m20 is sometimes strong, and sometimes it is not. What happened?

As soon as you check whether the oil pressure is normal, I suggest you replace the gasoline filter.

Whether the three-way catalysis of the exhaust pipe is dispersed or not leads to the blockage of the exhaust pipe sometimes.

Have a nice trip and good luck. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
