Why does my car dies out after i rev it?

If your car dies out after revving the engine, it could be due to several issues. A common cause is a faulty idle air control valve, which regulates the engine's idle speed and can cause stalling when it malfunctions. Additionally, fuel delivery problems, such as a clogged fuel filter or a failing fuel pump, may not provide enough fuel after high revs. Lastly, issues with the ignition system or vacuum leaks can also lead to stalling under certain conditions.
