How to Solve the Abnormal Noise When the Car Stalls?
1 Answers
When the three-way catalytic converter stops working, the temperature will drop, causing thermal expansion and contraction of its internal metal components, which then produces abnormal noise. This noise cannot be eliminated. If the screws at the interface of the three-way catalytic converter are loose, simply tighten them. If the carbon canister solenoid valve is damaged, replace it with a new one.
