What Causes a Car to Shudder and Gasp?

[AngelaAnn]

The reasons for a car shuddering and gasping are as follows: One-way valve blockage: A clogged PVC one-way valve prevents the timely discharge of exhaust gases from the crankcase, causing them to exit through the crankcase intake and reach the throttle position. Over time, this leads to symptoms of oil deterioration in the throttle. It is recommended to replace the PVC valve promptly. Control valve not sealing properly: The carbon canister control valve does not close tightly. Issues with engine mounts: Idle shuddering may be caused by problems with the engine hydraulic mounts. After replacement, test drive to see if the symptoms are eliminated. Sensor failure: A malfunctioning water temperature sensor can cause issues with the air-fuel mixture concentration.
