Sounds like a vacuum leak. The spring on the throttle should take one revolution to wind. That's all. So if you have tension on it, you should be good.

Sounds like that too.Originally posted by IsaacHayes View Post
I might have ef'd up the butterfly a little, when i swapped them, could that be causing problems also? Let me know..Comment

It is posible because it could be letting more air through the MAF than what should be going through. This could cause the computer to hunt for the correct idle RPM. Also make sure you have the TPS hooked up and it is on correct. Someone who knows these computers better than me can hopefully shed a little more light on this. I have read other threads about idle relearn but have no idea if that would apply here. I had no problems with idle once I put the 3100 injectors in.
If you have checked for any posible vacuum leaks you may have to look a little closer for something like that. Keep in mind you could have a vacuum leak around your fuel injectors or the upper intake could have a damaged gasket. Sometimes you can hold a hose(like 5/8 coolant hose) up to your ear and search/listen around the motor with the other end for leaks. This can make it easier to pin point where a leak is coming from.Comment

Did you use new o-rings for the injectors?sigpic New 2010 project (click image)

<<<<< IT LIVES >>>>>
I drove it home.. lovin the speed... but still being carefull... hehe
at this point time i have 2 issues.
1. I need the egr valve bracket ..
2. and my idle is too high.. the set screw is in the all the way in.
we are looking into shaving some of that off so that we can bring it in more..

The idle screw isn't for idle, just stops the plate from wedging in the bore....
You must have a vacuum leak somewhere.sigpic New 2010 project (click image)

Also, maybe someone else could help you/me with this but could the computer be looking for the EGR valve and because it is not there could that be a problem? Would it help to hook up the EGR valve to the harness and just tie it off to the side till he gets the adapter?

Having the EGR completely removed from the engine (and the passage properly blocked off) will not cause any idle issues. My EGR has been sitting in a box in the basement for over 4 years now, and all I get is an occasional SES light.-Brad-

Your knowledge is unfathomable ...
Ok so the "throttle screw" is not for throttle.. funny..
okay then..
the so if i take off the air tube i should see the butterfly sitting nice and snug in there..
and as for the vacum leak.. can't find any..
I have the egr area on the plenum blocked off with a piece of aluminum and a BIG ASS bolt in the hose the house that came out of the exhaust...
so no it is not blowing back into the plenum...Comment

Yes that's just the throttle plate stop screw. It stops the throttle from closing too much and causing the plate to stick and wedge in the bore. The computer adjust the idle with the IAC motor.
BTW the store here has EGR adapters in stock now.
What did you seal the EGR plenum hole up with? Just bare aluminum? Use a gasket or some RTV if you haven't... Hmmm Do you have a spare IAC to swap out into the TB? You should from the 3400 or your old one. Maybe it's bad and is stuck open?sigpic New 2010 project (click image)

ok.. i used the gasket that was with the 3400 egr..
Also what the heck is a IAC?Comment

WTF, i can't order from the store...
No ssl cert on the website? Why?Comment

IAC : http://wiki.60degreev6.com/index.php...alve_.28IAC.29
As far as the SSL cert, please don't bring that up. When we first transferred over to the new server, we bought an SSL cert for the store and could never to get it working properly. We even had the hosting company look at it with no luck. I thought Ben had finally figured it out, but maybe not?-Brad-

I think for the first time in my life i am going to buy a part on the interweb without an ssl cert... dude if you need some help with the cert i would be more than glad to lend a hand..
is the box a windows box? we can go off this into private message if you want..
and that IAC thing looks like my issue.. i do have the other one off of the old other one..Comment
