Ok, so if the first line down from 1k is 750, I'm actually sitting below 500 still. I'll have to figure out what the deal is with low idle, maybe i'll do that motordyne pedal dance tonight too.. you have a link to it?

OK, i think i got the ECU to reset based on initial idle after the pedal dance. However, once warmed up, the idle was the same.
I performed the idle air re-learn, and it was fine the whole time i drove it, turned off once i got home, started and back to high previous idle again. I'll try the battery off this weekend if all else goes according to plan.

Hey guys, I know this thread is probably dead, but I read it because I had the same problem and I'm sure other people will read it too...
I cleaned my dirty TB yesterday and all day I had the SES light issue... I just disconnected the battery over night, reconnected the battery, let the engine warm up, and then I performed the idle relearn procedure properly (with a watch). The end result was a nice 600rpm idle.
I really dont know what nissan was thinking when they created this technology, but I long for the old days where all you needed was screwdriver to set your idle...

Camilo is showing his age - sounds like he knows what a carburetor is, lol. As far as the problem, I had a similar problem only it was too high of an idle. Reset would only work until next time I started the car. Couple months later the TB died - replaced with a rebuilt OEM from Nissan for $170 and never a problem since.

Mine happened after a clean as well, however, it wasn't until a few weeks after the clean, in fact, maybe even longer.
Having said that, it was high when i got the car, i fitted the MD 5/16th spacer, and it was great for a couple of months, then after messing with my exhaust (back end) it went high again.

So the problem you had was exactly the same as i have, it won't remember between starts.
How did the TB die in the end? obviously or?

Drove my car all day today and the idle stayed low and slow.
When I was doing research on this matter, I noticed that Nissan put the same TB/ECU system on most of their cars and everyone is frustrated.
The only ones winning from this is the dealers. I bet if I went to the dealers here in Miami, those sharks would tell me I need a new TB, MAF sensor...ect.
This all just sounds like a Jiffy Lube scam lol
