Dongfeng Honda has run more than ten thousand kilometers. What is the reason for the loud noise after starting?

1, but if the roar is loud, please check whether the engine foot is damaged and can't play a damping role, resulting in excessive engine noise.

2. Listen carefully. If it is in the exhaust manifold, then you should check the exhaust manifold gasket and trace it from here to the end of the exhaust pipe.

3. If you don't trust, clean the throttle first. This is convenient, and the price is only twenty or thirty yuan. 4S shop estimates 50 yuan. Besides cleaning, they will also do computer matching for you.
