SOURCE: 2002 nissan altima p0507 idle problem

I had the same problem before. after using the scanner i got a code number P0507. "Idle Air Control", New 2002 and up Nissan models like my Altima don't have an idle valve or sensor like older models to be replace. Here's the solution " Replace your "Throttle Chamber" the idle sensor is build in it, there is no other way to fix this problem. the throttle chamber is about $175.00 at your Nissan Dealer. The need your core or you will need to pay extra money. No need for expensive mechanic shop, you could do this your self. the throttle chamber is so easy to remove, four screws holds it together. I will take you about ten to twenty minutes to replace it. Please trust me and you will save big bucks!!!!!

One thing is to leave the IAC adjustment alone, you have a vachum leake betweent the mais air flow sensor or a intake leak.

My 06 Chevy Equinox is idling high. How can you reduce the idle. It's at 3,000 RPMs just sitting still.


The number one cause for high idle is an imbalance in air pressure, An engine that is idling too high may be caused by a faulty idle air control motor valve that has completely failed or that has simply become weak and is not functioning correctly. God-Bless!

1999 oldsmobile intrigue stalls and surges under deceleration conditions only. Idles in neutral fine, accelerates fine, has no apparent miss. Can put in gear and travel great until under negative torque...


Do you have any codes? If so, what are they?
If not, this could be a mechanical problem with either the torque converter itself or some sort of stuck valve in the valve body inside the transmission.
I just replaced the valve body in my wife's 1999 Mercury Sable and it cleared up a number of problems she was having with shifting and torque converter lock up.
I hope this helps.
Good Luck!

At times my car idels a little high and when you let off the break it accelerates by itself more than normal


this is a pretty common thing,, when applying your breaks , the brake booster requires more vacuum to work, which takes the vacuum from the motor,, once released the motor gets the vacuum back,, so it will rev up a little, If your familiar with working on cars, remove the throttle body air duct,, spray a little carb cleaner ( a little not a bunch) into the end of the throttle body opening, there is a governor plate inside that gets gunked up, and will make the cars idle jump around at times, clean that and you should be fine !!

Will idle high sometimes up to 3000 rpms when driving or sitting still


I have the same Jeep and same problem. The engine was running rough. The Jeep dealer fixed a vacum problem in the manifold and they then decarbonized and cleaned the fuel injectors. After these repairs the idle problem began, it would spike to 2000 rpm while sitting at idle, sometimes it would slowly come down, sometimes I would have to tap the accelerator. I took it back in and they then replaced the throttle motor and reprogrammed the PCM (Power Control Module?) Still same problem. Now they suspect a another vacuum leak and I am taking it back in on Tuesday, will let you know what happens, $ 1,300 so far.
