Car doesnt idle?

Hello,

It sounds like there is an issue with the idle air control valve.

The idle air control valve is located on the throttle body.
That valve controls the idle and when it becomes dirty it can have an impact on the idle of the engine.
Overtime the larger air particles will get stuck inside the valve and that will restrict the air flow, leading to an idle issue.
Typically, the idle air control valve can be cleaned out and that could improve the engine idle.

Here are few helpful articles:
