Where is the idle adjuster on a 1997 Camero?

The 1997 Camaro, depending on the engine (V6 or V8), doesn't have a manually adjustable idle air control screw like older carbureted engines. Instead, the idle speed is controlled electronically by the Powertrain Control Module (PCM). There's no readily accessible "idle adjuster" you can turn.

Issues with idle speed on a '97 Camaro are usually addressed by diagnosing and fixing problems within the electronic control system, not by adjusting a screw. Possible causes include:

* Dirty Throttle Body: A dirty throttle body can interfere with the sensor readings and cause idle issues. Cleaning it is often the first step.

* Faulty Idle Air Control (IAC) Valve: This valve is controlled by the PCM and regulates air flow at idle. A faulty IAC valve is a common cause of idle problems.

* Vacuum Leaks: Leaks in the intake system can disrupt the proper air/fuel mixture and affect the idle.

* Faulty Mass Air Flow (MAF) Sensor: This sensor measures the amount of air entering the engine; a faulty one can throw off the fuel mixture.

* PCM Issues: While less common, problems with the PCM itself can also affect idle speed.

To fix an idle problem, you'll likely need to use a scan tool to read diagnostic trouble codes (DTCs) from the PCM. This will help pinpoint the source of the issue. Taking it to a mechanic or using a professional-grade scan tool is usually necessary for proper diagnosis and repair.
