What causes a infinity i30 to idle low?

A low idle in an Infiniti I30 can be caused by several factors, including a dirty or malfunctioning idle air control valve (IAC), vacuum leaks, or issues with the mass airflow sensor (MAF). Additionally, problems with the engine's fuel system, such as a clogged fuel filter or failing fuel pump, can also lead to low idle. It's important to diagnose the specific issue using a diagnostic tool or by checking for error codes to address the problem effectively. Regular maintenance can help prevent these issues from occurring.
