RPM problems on 1997 Jeep Grand Cherokee

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My car is having problems when the rpm's drop below 500 the car turns off. So I need to know where the idol screw/pin is so that I can turn it up so that the cars stops dying and so I don't loose power steering because the rpm's are too low thanks

I had a similar problem. You might want to consider checking your Cam Position Sensor.

The Idle speed is actually controlled by the IAC or Idle Air Control valve. It's located on the throttle body and depending on which engine you have it's in a few different spots.
The idle is adjusted by the PCM according to what the IAC reports.
