    I've had the same problem for quite some time, and have been researching for approximately 5 months for a solution. I've just recently been told I have a short in my Idle Air Control circuit. I was also not aware that this vehicle even had an EGR valve on it, I've yet to see that in my repair manual. Or perhaps I've over looked it. Any other suggestions to solve this problem would be helpful. thanks.

What does the MIL code "PO 320" mean, please?


code p0320 refers to cam shaft position (CKP) sensor/engine speed (RPM) sensor--circuit malfunction=== causes --wiring--CKP/RPM sensor ---ECM
because the engine runs ok until it is on cruise control I would be investigating the RPM sensor for a fault
The cruise control takes its control from the RPM sensor and if that circuit is interminable the the cruise control doesn't know what rpms to maintain.

The tachometer shows 900 RPM on idle position but as i put the car in gear and release the clutch the RPM drops and u have to race the car manually through accelerator pedal.recomend the diagnostics a


The engine does not need to be raced when cold

The vehicles computer will adjust the idle according
to how the manufacture programmed it

After about one mine or so, the idle on most vehicles
comes down to approx 750RPM, generically speaking

When you put the car in gear,assuming it is an automatic,
the rpm will drop a 100 at most & may be adjusted by the
computer, just as it does when you put the A/C on. That is
to compensate for the change in engine load

You should be waiting for the rpm to come down to 650 to
800 & then a couple more minutes for some temp to come
up, before driving off. In cold weather wait at least 5 min or more

I think your vehicle is not working correctly, or you not explaining
it in a way I understand what answer you want

Why would the rpm for my 1997 Nissan Maxima go down to 550 when the car is in the idle position? The RPM's of my car go down to 550 when the car is at a stop light.


I don't really know where they should be in idle on your car, but if you don't apply your gas pedal, the RPM's should be low. My 18 wheelers RPM's are down to 500 in idle position and go up to 2300 when I step on my "diesel" pedal. If in neutral or park and you step on the gas...do your RPM's go up? If yes, all should be okay.

RPM problem


Check and lube the Idle Air Control (IAC) valve,

This tiny electric motor is mount on top valve cover and close to the accelerator cable.

The function of IAC motor is to idle up the RPM when more load is added.

Example: A/C on,light on,stop light on and radio on.

A stuck IAC can be free by few soft tape on the body of the motor.

To lube the worm gear,you will need WD-40 to free up the old grease and lube white lithium grease.

Clean the electrical contacts with CRC electric part cleaner.

This electric motor is very expensive.

Please handle it with care.
