So I just installed a Motordyne ISO gasket Spacer (5/16). Since I was in there with the parts off, figured I'd go ahead and replace the spark plugs and clean the throttle body (which was MUCH needed).

Put everything back together, torqued to specification, double checked all connection, no left over bolts lol, etc. Started up fine...Did the ECU Accelerator Pedal Reset Procedure, The Accelerator Pedal Release Position Learning, Throttle Valve Closed Position Learning, and the Idle AIR Volume Learning. Car seemed to perform good and idle was normal. Took it for a test drive and while at a light, the SES came on.

Went back to the house and repeated the above procedures...SES light went back off (did it clear it?). Drove it around again and all seemed fine...let it idle a while and still ok. Go workout this morning and get back in the car...SES is back on! Had Autozone run the code. "Idle speed control system RPM higher than expected."

Is it possible (this is my hope) that I just didn't get all of the above procedures right...with the times I mean? Or did I mess up the TB cleaning it? I didn't use a spray at all...just some alcohol on a rag...and yes I moved the butterfly valve to clean it but I was very careful.

Also, I thought I would mention this...when I had the plenum off and was cleaning the "excess dirt and oil off...I actually cleaned it to the point where you could eat off it...no oil at all on the surface. Is there supposed to be a little oil on it?...that shouldn't have anything to do with the idle though right?

Any help would be appreciated. Thanks

 

Think I got it fixed guys...My idle is actually lower than it used to be before the spacer, plugs, and TB cleaning lol. It took me a few times and a few extra steps found in our forums that ARE NOT mentioned in the Motordyne instructions :\ If anyone else has a problem with the idle air procedure and it isn't working, I will post those extra steps, cus I have seen several that looked like what Motordyne sent to me.

Anyways, I think I got it fixed, we will see in a few days...but the idle actually did change this time though.

 

Did it work? Can u post all the steps? thanks

 

idle air relearn is easy if you have the right tool, the shop I go to has Nissan console it does everything its a few thousand dollars but makes easy,
