What to Do If the Car Shakes After Refueling?
2 Answers
Poor performance of the ignition system or bad spark plug firing can also cause the issue. Solution: Replace the spark plugs. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can lead to car shaking. Solution: Replace the components if necessary. Replace around every 10,000 kilometers. Delayed replacement can cause insufficient air intake, leading to low idle speed and engine shaking. Simply replacing the filter element can resolve the issue.
I recently encountered car shaking issues after refueling. That time after filling up, I noticed the engine was trembling like it was dancing. I immediately realized it might be a fuel quality problem, as the newly added fuel could contain impurities clogging the fuel injectors. I parked and turned off the engine, then restarted to test, but the situation worsened. I checked if the fuel cap was tightened properly and found no issue, so I drove straight to a nearby repair shop. The mechanic inspected it and said the fuel system needed cleaning, also recommending using higher-grade 92 or 95 octane fuel in the future to avoid similar situations. Additionally, if your car isn't compatible with ethanol-blended gasoline, it can also cause shaking—you can try adding a bottle of additive to improve it. In short, not addressing the shaking promptly can affect safety and even damage engine components, so don't hesitate and get it checked as soon as possible. Safety first, after all.
