Is it necessary to do throttle cleaning for Mai Rui Bao 2.4?

Yes, you need to see the tachometer. If the pointer swings up and down, it means the throttle is dirty. If it is not cleaned, the engine fault will light up. Mai Rui Bao usually needs to be cleaned once when it does not exceed 15000. I hope it can help you with your car problem. Ask the car master. 4S shop professional technician, 10 minutes to solve.
