Severe Engine Shaking After Refueling?
1 Answers
Possible causes are as follows: 1. Engine misfire: An engine misfire mainly refers to one or more cylinders not functioning properly. Common symptoms include intermittent exhaust gas flow with noticeable shaking in the exhaust pipe, distinct engine vibration, and sometimes accompanied by sputtering sounds. This is often related to ignition coil failure. 2. Worn or loose engine mounts: Engine mounts are rubber blocks placed between the engine and the frame. Their purpose is to reduce vibrations and absorb shocks during engine operation while securing the engine in place. If these mounts become worn or loose, engine shaking can become significantly worse. 3. Ignition system issues: Check the condition of spark plugs, high-voltage wires, and ignition coils. Poor performance in the ignition system or improper spark plug firing can also lead to such problems. Solution: Inspect spark plugs for excessive carbon buildup and replace them if necessary. 4. Unstable fuel pressure: If you have already cleaned engine carbon deposits, cleaned the throttle body, replaced gaskets and spark plugs, but still experience body shaking at idle, the issue might lie with the fuel supply pressure or the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings from the intake pressure sensor can cause body shaking. Solution: Check fuel pressure and replace components if needed.
