How do you fix the idle air control system RPM higher than expected?

Check the PCV valve as well and see if it is blocked and needs a new replacement. Inspect the IAC (Idle Air Controller) if it is equipped, and verify its performance. Try swapping in a new throttle body (if available) and see if it can fix the problem.

What does System Too Lean Off Idle Bank 1 mean?

The P2177 code means that the system is too lean off idle for bank 1. What that tells us is that the air-fuel mixture is too lean for the bank 1 half of the engine. This failsafe mode is enabled to protect the engine from damage and sets a fixed air-fuel ratio to prevent the vehicle from becoming too rich or too lean.

What happens when your IAC valve goes bad?

The idle air control valve is programmed to regulate and maintain the engine idle speed at a constant rate. If the valve fails or has any issues it can cause the idle speed to be thrown off. This may result in an unusually high or low idle speed, or in some cases a surging idle speed that repeatedly climbs and falls.

What are symptoms of a bad IAC?

When the idle air control valve fails, it inhibits the flow of air through the engine. When the car can’t receive air, it leads to engine stalling. The severity of this symptom can range from occasional stalling at first, to stalling immediately after ignition.
