Why does my maxima IACV run too fast?
If your Maxima’s engine has developed an air leak somewhere in the manifold or throttle body, the computer may close off the airflow that is coming through the IACV in an attempt to hold in air and maintain the proper idle. Too much air will cause the vehicle to idle too fast, increasing the engine’s RPM reading at an idle.
Why does my maxima not accelerate when the RPMs go up?
If your Maxima won’t accelerate, but the RPM’s go up it’s usually not going to be an engine related issue. Somehow, the power that your engine is creating is not making it to the rear wheels. This is typically a transmission related issue. Here are the most common cause of acceleration with the RPM’s going up:
What should the idle speed be on a maxima?
Problems with the IACV will cause your car not to idle properly or even to stall out. The Maxima should idle at a speed of approximately 1,000 RPM when it is not in gear and 800 RPM when it is in gear.
What causes a vacuum leak in a maxima?
Vacuum leaks will affect the amount of airflow your Maxima’s idle air control valve is receiving and can cause the vehicle to idle both too high and too low. Vacuum leaks are not actually a problem with the idle air control sensor itself, but with the connections to and from the control sensor through the throttle body and intake.

What is the idle air control valve on a Nissan Maxima?
The idle air control valve, or IACV, in the Nissan Maxima is responsible for regulating the amount of air that flows through the throttle body to maintain a constant idle speed. Maxima’s powertrain control module controls the IACV electronically.
