I like this one more than the old ones.  Nice find, maybe sticky worthy.

yeah the prep section is what i like most.  this is gunna replace the old how-to.  sticky!

Thanks for this - you saved my car from it's own Obsessive Compulsive Disorder twitch.

I had an idle problem on my 2005 SE-R SpecV in which the car would repeatedly rev to 2000 RPM, drop to 1500 and bounce back to 2000. It would do this any time the revs got below 2000 and the accelerator pedal was all the way out.

I did the re-learn procedure and at first it appeared like it had not fixed the problem. I revved the engine a couple times as it says in step 12 and it was still doing it.

*** Then I tried holding on the brake and slipping the clutch in 1st so that it would slow the engine down to the specified RPM range. Suddenly the car stopped revving itself and it hung at the perfect idle RPM. It seems to be fixed now.

10. Start engine and let it idle.

11. Wait 20 seconds.
 
12. Rev up the engine two or three times and make sure that idle speed and ignition timing
     are within the specifications. (700±50 rpm)

13. If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried out successfully. Further diagnosis may be required.  *** It may be necessary to force the engine to idle at the desired rpm range to cause the relearn to happen. ***

you aren't doing it correctly then.  keep trying.  use a stopwatch if you have to.

When you're right, you're right. I got the whole procedure to go through! the idle is back where it should be and stays there!

This was a bit frustrating, but it worked eventually!

I assume that this DTC takes a certain number of trips/parameters to be reset. I'll have the boys at AZ clear the code in the morning.

Thanks Guys

PS>> I'll try to post a video of Me pig-blapping the service manager at Lancaster Nissan ASAP

lets just say that this is THE biggest pain in the ass to do but i got it done after about 2-3 hours...

one thing though... my safc only reads 91% throttle when im at WOT. what could be wrong?

Your throttle position setting was probably so far out of wack that you will need to re-initialize your safc, and redo the safc throttle position test.  Just follow the how-to for safc setup.

My car does this but only stays up for like 5 seconds then drops and idles perfectly.

Anyone else like this?

I completed an I/H/E install recently and did move the 2nd o2 sensor. I got my SES light to go off and am idling at 750. However, sometimes after accelerating and then coasting, the rpms will stick at the high number before coming down to 750. Will this process help that?

It should

It did!

I asked cause I had gone out to try it and did not get the SES light to blink. Why go through all the trouble of getting the timing down if it doesnt matter? Of course the first time I tried it after posting the original message it worked perfectly.

OMG That was a great post!! My RPM's were at about 2500 i tried the other post it didnt work but i tried yours and it worked great car is back down to its normal idle thanks alot man. OHHHHH btw got the engine back in my car today so its up and running again but when i started it, it just reved high and would not go away so thanks again man

I tried doing the procedure, but for some reason every time i would do it I couldn't get the damn SES light to blink? Any Suggestions of what I might me doing wrong.

****My situation is that when i allow the car to coast, the RPM's bounces back and forth between 1500-2000 and then slowly goes back down. Trying to solve this prob by using the procedure.

You have to time it fairly precisely.  Use a watch or count 1 one thousand, 2 one thousand.

I guess my timing is off....I'll try it again. Ill let you know if i made it through...Thanks Don

My car idles at 1500 after cleaning out the throtte body. Never had a ses light come on and idle relearn procedure doesnt seem to work. Any suggestions besides replacing tb.

i just did this, worked like a charm on the first try. i love this site more.

i can get the light to blink every single time. but i dont think im doin the rest right because its not cooperating lol

ok so i did the relearn but then the SES light came back on tried it again but for some reason step 8. didnt go through .   


8.Wait 7 seconds, fully depress the accelerator pedal and hold for approx. 20 seconds untill
      MIL (Malfunction Indicator Lamp, a.k.a. SES light) stops blinking and is turned ON.


any sugestions

When you finish the relearn you have to clear the code that you threw
