Have you ever pressed the gas and watched the RPM needle spin around like a disco ball? Although it's not usually a symptom of serious trouble, a dancing RPM needle can be concerning.
A vacuum leak or a fuel injector issue are the two primary culprits. The air-fuel combination loses equilibrium when a vacuum leak lets unmetered air into the engine. This may result in a dancing RPM needle and unpredictable engine performance.
The engine may stutter and the RPM needle may leap due to problems with the fuel injectors, such as blockages or leaks.
Don't disregard an RPM needle that is dancing. To identify the issue and stop more problems, have your car inspected by a professional.
