I've been driving my Civic for over three years now. Last time, the idle was shaking so badly it gave me a real scare. I immediately pulled over to check, starting with the simplest thing: I pulled out the spark plugs and saw they were all blackened and worn out. I tried replacing them with a new set, and the shaking improved significantly. But it wasn’t completely fixed, so I went ahead and cleaned the throttle body—there was a thick layer of carbon buildup. It took me about half an hour to do it myself. Later, I noticed the engine mount was a bit worn out, so I went to the shop and replaced it with a new one. Now, the idle is rock steady and gives me peace of mind. Honestly, idle shaking is just a minor issue—the Civic is a tough car. The key is regular maintenance; don’t slack off. Don’t skimp on things like changing the air filter either, or you might end up with dangerous shaking on the highway. Pay attention to your car’s condition, and it’ll take you much farther.
