What causes the rough engine idle o r vibration in my Suzuki Khyber?

The engine vibrates a lot when idling, and sometimes it stalls when I stop at signals, especially if the A/C is on. It runs better when driving, but idle remains unstable. I’ve cleaned the carburetor and checked the plugs, but the issue is still there. Could this be due to bad engine mounts o r a weak ignition coil? What’s the best way to identify the real cause?

Engine vibration at idle is often due to worn engine mounts, misfiring plugs, o r a dirty carburetor idle jet. If the RPM is unstable, the idle setting screw may need adjustment. Also, if the engine stutters more when A/C is on, it could be a weak ignition coil o r low compression in one cylinder. Clean the carburetor thoroughly, replace plugs and check plug wires. If mounts are cracked o r loose, they should be replaced immediately to reduce engine shake.
