Hello, it depends on perspective, but this engine will make a bit of a rough idle normally. However, if it's abnormally rough, a diagnostic test for engine performance will be needed, checking fuel delivery, ignition spark, air intake, emissions controls, engine timing and compression. Additionally, worn or broken engine mounts can cause extra vibration.
