Stupid me decided to clean out the TB. I cleaned it out with the car running and now the car is idling high. I simply sprayed TB cleaner into the butterfly but used my hands to move it. It's still fast as hell though so I don't think the ECU reset the timing. I read the stickys and also did a search and read some nightmares of dealers replacing entire TB's. I was wondering if anyone found an easy solution to reset the idle. I also have a Jet ECU upgrade. Will re-setting my ECU effect my programming that Jet did? Damn I can't catch a break lately.

Thanks in advance. I apologize for so many new topics but I just got my 02 and am finally a member so I can search the archives before posting now.

 

Hmmm. Read some more about a guy who had a similar problem. He brought the car into the dealer and the dealer removed the sensor on the MAF to get the idle down. He said that the mechanix had to reset the ECU to get the car to keep the idle down. I just tried removing the sensor and the idle did go down. I got back in the car and had no power. I would press the gas peddle and it wouldn't rev. So I shut the car off and re-started and the idle stayed down around 600 rpm's and it would then rev. So now I have to get rid of the CEL and I'm set. I think.........

 

I thought touching the butterfly will screw crap up?

 

i remember measuring and messing around with the butterfly in blubyu2k2's old maxima. no high idle after opening and closing by hand. you should not have to worry about resetting anything the jetchip did because to be honest, it did not do anything in the first place. the best description of that ecu is getting your ecu back with a sticker. i would try the reset first and if that does not cure then take it to the dealer for a sitdown with the consult 2.

 

Too the car out for another spin today. I was working on it at 2:30am last night. Anyway the idel is around 900rpm's. I believe that is normal. I tried the ECU reset instructions but no luck after 10 tries.

1. Turn key to on and wait 3 seconds.
2. Stomp pedal 5 times in 5 seconds.
3. Release pedal and wait 7 seconds.
4. Depress pedal until light flashes, etc.

 

1) when you touch the butterfly, you have to have the idle recalibrated and that can ONLY be done with a consult II. it's electronicaly controlled.

2) you were probably reading my thread. when my friend cleaned my TB, even with the consult, the car would not drop back to normal idle (btw, it's 625, NOT 900) so in order to force it to drop lower, a trick done was to disconnect the maf while the car was on, then plug it back in. that dropped my idle from 900 to 750, and then when the consult II did the re-idle, it finally caught onto 625 and stayed there.

3) simply put, you aren't damaging the car by high idling, but it would be nice to set it back to normal. they can recalibrate it w/out resetting the ECU. let's not go into the details of what the JET can or cannot do.

 

maybe i was lucky then. we did not have to do the pedal reset or idle recalibration afterwards. i opened and closed it many times to fit my hand behind and on top of the butterfly and the idle was the same as it was before.

 

definitely got lucky. i can't account for what happened with you, but seeing as my friend is a service manager and had the consult with him, i can't do anything but agree with him. it does make sense that it would "wack out" of sync, seeing as it's electronic and not a traditinoal cable throttle, and oddly enough, you were fine.

 

I foolishly cleaned mine as well and I experienced high idle and a jump in rpm's as I slowed down. The rpm would keep spiking up as I slowed down. I did the accelerator and idle air pedal learn and it seemed to help with the high idle. However, the RPM jump was still there. I was also pulling P0113 immediately after I cleaned the TB. I finally gave in and took it to the dealer and got the usual bs from them. "Well it's your aftermarket intake" and "The oil from the intake is the problem". Same ****, they kept on saying my MAF was the problem and it was dying. I told them I had just changed the MAF about a month ago and that it wasn't the problem and there are MAF specific codes I would pull if it was having problems or bad, P0113 is not. IT is IAT high input which is located in the MAF I believe but i told them I only pulled this code after i cleaned the TB. So after some more bs from them, I told them, like I initially did, to just perform the Idle Air Procedure. So they finally did and the rpm thing still shows up sometimes but does seem better, not as drastic, and I haven't pulled P0113 since I had them reset it last tues.

 

Epacy - did you also reset your ECU or did you just do the accelerator and idle air pedal learn procedure? What RPM is your car idiling at? Mine is at 900. I believe 600-700 is normal.

 

On Gen. 5.5s don't try moving the throttle plate by hand. Go IGN. ON and use the pedal. Any servo operated component i.e. throttle and IAC valve should not be manhandled.

 

OK. My high idle from cleaning my TB is all fixed. I went to: http://www.technosquareinc.com/350reset.htm and followed the procedures on this page and all my problems vanished. Idle is back to around 600 RPM's and the CEL is off. Lets hope it holds but I think it will. Just goes to show you how many people have been ripped off my the dealer. I read contless posts about users cleaning their TB and getting a high idle. Many of them were told, by the dealer, that they needed a MAF, a new TB, etc. This is why I hate the dealer. Their salesman are trained to lie and many of the service repas are theives too. I'm sure there are good dealers around but.....I once had a key programmed and went home to discover that all my other keys didn't work. YOu would have thought that the dealer would have told me that programming a key to the car will wipe out the previous program and that the other keys will not work.

 

High idle did return. My mechanic said that I need a new Idle sensor. I'm not sure if he's right. Anyone change this sensor for a fix?
