What does your max idle at?
For some reason looked at the rpms the other day while I was at an intersection and I was idling at 500 rpms this seems kinda low in my opinion. Is this normal for you guys? If not is it a big problem and how should I fix it? Thanks in advance

That's low for even a manual, which by FSM can idle the lowest.
Recommended, no load, warm idle varies a little bit by years but still is around...
MT 550-650 rpm.
AT 600-700rpm.
Weather outside controls my idle (sometimes I can predict the weather based off of it)...
550 for good weather days and about 700 for bad days.
And warming up... My car has idled @ 2k many times before, but those days were extremely cold..... Houston has never seen any temps near what the car saw in KS, the highest I've seen it idle down here is 1.4k, and that was once. Usually the first start of the day it roars to 1.4k and calmly backs down to 1.2... then lower and lower....

My auto idles at 1200rpm cold & 600rpm warm.
On a warm engine just open the IACV adjustment screw a little further to increase the RPM. It's a black plastic screw on the top left of the Idle Air Control Valve.

you need to also disconnect the tps, and make your idle adjusment via the IACV.

If I give my maxima some gas , and revv above 2k rpms and let off quickly the idle drops to 4k and stalls a little and comes back up , what could this be?
My maxima idles at 550 rpm with no AC and I usually put my ac on 1 so it idles correctly (700-750 rpm.)

based on this you think its most likely the dirty TB?
Is there a good write up link on cleaning th TB? the one in the how to does not work. and on my honda you just unplug IACV (not even sure my max has IACv since its auto...) and take off 4 screws and 2 hoses and its done. looks a bit more menacing on the max.

My car used to idle a bit high and so I lowered the RPM with the IACV screw and then after cleaning the TB it went back to stock idle. LOL
So here is the low down:
Cold RPM-1200
Warm- 800
In gear- Somewhere between 500-600
I thought lowering the RPM would save gas, but it didn't make much of a difference

Since replacing my knock sensor, all of my issues have been resolved...hesitation, idling issue, and poor gas mileage.

Speaking of gas mileage, I'm new to the forums, what kind are you getting? I feel like my 98 maxima auto gets about 21 mpg. I feel like I keep it fairly well maintained, so I'm curious what others are getting.
