need help idle jumping all around

[droppedlow]

First off I searched all around and not one thing that is like my promblem. I just got done rebuilding my engine and I have done about 6 or 7 bloost leak test to get rid of all of them. I start my car and it starts up just like every other time but as soon as it gets warm the idle jumps from 1100 to 2000 and i cant figure out why. all my sencers r new and all checked out fine.

any one please have been doing this for over a week now.

Did you happen to check this article http://www.dsmtuners.com/forums/newbie-forum/117761-jumping-idle.html
Also you said you have new sensors so i'm guessing that you have a new tps set correctly right?... also what about your oil pump.

Sounds Like A Bad Iac Sensor.. Replace It!

yes i have read that. yea tps is set and new .63v, and there is a new iac in there too. yea just rebuilt the enginge new everything in the bottom end. profile is up to date.

you should try that fiav block off plate. Tons of information if you use the search button.

this may sound stupid. your throttle body is geting coolant right? i know someone who thought he knew it all and wleded it shut and the car did the exact same thign

 

[droppedlow]

fiav is done and no the tb does not get coolent anymore. I put a short piece of hose on there. it will idle w\out the maf plugged in.

How's the timing - both belt and CAS? timing issues can cause the ECU to fight for idle.

 

[talon187]

thats why then the throttle body needs coolant

 

[droppedlow]

ok timing is fine and for the tb getting coolent i know 3 ppl that dont run the lines. why would i run them when i am trying to get intake temps down and you have hot coolent running there. dustin from slowboy is a really good friend of mine and knows dsm's and he doesn't even know whats going on with it.

ok after not looking at my car for 2 days i went back and did a boost leak test and found out that i had 2 injectors leaks and my throttle body seals where too.
