the car MUST be at operating temperature for any of the relearns to actually take effect.
Thats why the OP could never get it to work. Your car will not relearn if you leave the battery unplugged over night and then try to idle control relearn on a cold engine.
The coolant must be above 70C (160F)

I noticed some weird stuff happening after cleaning mine, then I bought a can of electrics safe lube (probably overkill, basic lube would probably have been fine) from a Radio Shack and that helped with my issues.
I also hear the TB's going bad fairly commonly. Not to mention the possibility of a dirty or bad MAF after removing the tube and possibly being bang around. Aside from that stuff check for air and vacuum leaks.

had the high idle problem after cleaning the TB. My idle was around 1100. tried relearn numerous times with a stop watch with no results. I disconnected the battery overnight and started the car now and the idle is back to normal and where it should be around 850 (i have cams). i know im bumpin the thread, but i wanted to be helpful.

There are a couple of things people need to pay attention to here.
1) This is specifically for people who get the re-learn to work (instantly sets the correct idle speed when performed) But then the high idle problem returns after turning the engine off, then back on again.
2) Engine temp does have to be hot, so you can't do it when cold.
No, i can't set mine either.

I'm posting this same response in a few threads for this problem in the hope that someone else will benefit from it.
My idle problem is fixed, and by that, i mean the problem where it does not remember the correct low idle after turning the car off.
I did a couple of things differently during my last reset, which i'll explain below, but here's the points i used.
1) Car fully up to running temperature (required)
2) Reset performed per the book, correctly takes new idle setting (as normal each time i do it)
Two things i did/did not do this time that seemed to make the difference:
1) I turned off the interior fan before starting the procedure.
2) I did not rev the car a few times after the new lower idle had taken (even though the procedure calls for it)
I have no idea which of those two made the difference. All i know is, that it's now remembering the new idle and it's super smooth.
I had loaded a new map on the car a week previously, and i had the door open and the fans on low with the engine off for a few mins before starting it, i do have LED interior bulbs.
However, it complained of battery voltage too low and would not let me flash until i had closed the door and turned the fans off.
This has never been a problem before when flashing and whilst i don't think it's a problem directly, i'm wondering if it showed up another problem that perhaps contributed towards the issue.
The battery isn't that old but it's possible it's not as well as i thought, I'm thinking the battery voltage during the reset procedure, which is done with the ignition on but engine off, was causing a problem with the learning portion.
Short version;
* I came home and turned off the engine, fans and kept door closed.
* I ran the procedure, acquiring the lower idle, but omitting the rev testing at the end.
* Turned off the engine and shut the car up for the night.
* Everything perfect once up to running temperature the next day.
Hope this helps someone out.

Code P0507
i know im starting up a dead thread, but im having the p0507 code come up, i got it scanned by autozone and then came home and did the ecu reset. and it went off for a day and came back on, i never had a high idle at all, it was always normal. i took it to the local shop that i trust, and they couldnt find a leak anywhere or anything wrong. so i tok my car back and did all the resets and relearns and it came back on 7 hours later. i need help

I am having this exact problem as well. Idle's fine around 600rpm once warmed up in the driveway.... if I push the clutch in while rolling say around 55 mph the rpms will go up to about 2500 then drop to 900 then bounce back to 1500 and hover there until I let the clutch out. I have gotten multiple tps sensor codes and sometimes the throttle will stop working all together resulting in me pulling off to the side of the road, car will stall, hesitate to start again then start once it sits a couple minutes. When that happens the gas pedal will not work at all and I assume this it limp mode.
I am going to order a new tb soon and see if this fixes the issue. I have cleaned the MAF sensor, check all intake connections and hoses for leaks and performed all relearns too.
