Why does my car run roughly when driving but run smoothly in neutral conditions?

This could be a sign of several different issues with your vehicle. One possibility is that the ignition timing is off, which would cause the engine to run roughly when driving but smoothly in neutral. Another potential issue could be vacuum leaks or blocked fuel injectors, which can cause an uneven air-to-fuel ratio and lead to rough running conditions. A third possibility is that the mass airflow sensor, which helps regulate airflow into the engine, may not be working properly. If any of these issues are present, they should be diagnosed and repaired by a qualified mechanic as soon as possible to ensure safe operation. Additionally, other minor problems, such as clogged fuel filters or spark plugs, could contribute to the issue, so it is important to have a professional inspect the system.
