Cool thanks, well i managed to get the MIL to blink, but at #9 i think i mixed up the step

What i did was release the pedal as soon as the light remained ON

I will try again in the morning and let you all know, it's almost midnight here :)

Hey well i tried the manual way and it was not working. So i went to the dealer and they hooked up their computer to it but they said it was not "accepting the relearn procedure".

I took it to another place that does computer diagnostics and they spent about 3 hours with it and they managed to relearn the idle speed.

The guy said they had to scan the entire system then remap everything from scratch. I'm not sure what he meant but i'm glad it's back to normal again.

Note to self - NEVER touch the throttle body again :(

That's a good note to make for yourself indeed :)

I had the same problem when I fitted the piggy back ECU and the guys touched the electronic butterfly of the throttle body and moved it with their hands. It took me 3 times of visiting them again and again for them to get the idle right and even Nissan couldn't do it. It was accepting the re-learn fine but was not holding it for long. Am glad your mechanic had the patience to do it as the last time I did mine, it took the guy close to 45 minutes of fiddling around with the settings to get it right. You might want to add your mechanic to the list of trusted ones as he sure does know what he's doing.

Got an '01 3.5L Pathfinder. I cleaned the throttle body and now have fast idle and CEL code P0505 "idle control system malfunction". I repeatedly tried the manual 'idle reset procedure' avail online with no luck and quess I will have to take it to the dealership service department for the Consult II reset.

Any Nissan service tech that could verify I am on the right track? Any in Bham, AL that could shadetree this for me?

UPDATE

well, I could never get the self-prograamming function of the idle air relearn procedure to work. I must have done it 455X, timing it, etc. What a PIA. The dealer said it's $100 to pull in in the door so I took it to a smaller shop that has done work for me, stating they had the ability to do this. I hr later at $73/hr and I was on my way. When I mentioned to them that I understood this to be a 10 minute procedure, they told me the machine to do this was $6000 with $200 quarterly updates required.

Note to self: leave the TB alone in the future.

i did same thing, and pushed valve by a screw driver to clean. it lost idling point. then i went to Nissan and they recalibrate idling with consult device.

two weeks ago, car started to stall at start. i checked and found that TB was dirty again, i asked my friend to help me to turn on the iginiton and turn off. while it was adjusting TB itself, i sprayed brake pad cleaner and it worked. so it is possible to clean it without touching it. now it starts normally.

What a load of bullocks from the dealers and the mechanic. The idle re-set is done while you wait and takes no longer than 10 minutes using Consult II and a cost of no more than $10 bucks!!

Maybe so in Ozland... but here in Cunuckville it's by the hour.... even if it's only 10 minutes

It's by the hour in Australia as well, but the idle re-set and job similar to that have a fixed price because they know exactly how long it'll take them to do, so you are being ripped off.

I have read that other cleaners than somethng like Throttle Body & Air Intake Cleaner - JCWhitney can remove protective coatings on certain manufacturer's parts and damage O2 sensors.

Some vehicles have as many as (6) O2 sensors and with some in excess of $200 each, taking the steps to purchase and use the manufacturer's recommended cleaner could save one significant money in the short run.

thank you for information!

I never like paying more than I have to for anything. When all available options are similar, I don't look at it as "being ripped off" but moreso the price of admission.

You are getting a gift.

LOL :) A gift?

If no one will challenge them about that over-inflated price to do such a minor service, they will just continue on with giving you that "gift" and others as well ;)

All you need to do to prove your point to them is show them the print-out of the re-setting the idle using the manual process and state that if that manual procedure takes 15-20 minutes to perform without Consult II, why you're being charged for a full hour by them when they use the much easier automated process!
