hey every1,
JUST finished my NS conversion...and i go to start the car. No check engine lights or nething...but the car JUMPS from 2k to 2500 on idle. and even if i start it in gear, it tries to swing to 3k for AWS even tho i start it in gear...


does ANYBODY know what would cause this? any elect. sensors? btw, the only thing i did was remove the DT and took out that other throttle cable

teamstealth

anybody??

sure its not just your cold start????

let it idle for afew minutes and see if it goes back down...

if its not that, then make sure that your Throttle calbe isnt caught somwhere or over tightened... i doubt its that


also check the hose that connects to the MAP sensor.

its on the back right, of the car, its attached to the firewall, the black box. Make sure that the hose is still running to your UIM.

Did you do the poor mans job?

I agree, If its not he cold start then check your map sensor and the hoses attached to it.

teamstealth

the map sensor is fine...its on the sensor good and run to the backside of the UIM...the thing that gets me is im starting the car in gear w/ the clutch in....cold start should be eliminated. Not to mention, whos cold start JUMPS back and forth from 2k to 2500?

teamstealth

i did the full version, but didnt block off jackshit because i need all the emissions stuff

did you eliminate the double throttle???

I'm doing the full non seq as well, I'm going to start my car up tomorrow morning early, I've been waiting for my DP to come in which it did so we'll see how mine went.


I on the other hand did block **** off along with the removal of the flapper in the y pipe and the removal of the door in the wastegate.

you might want to check the hose to the PCV. Mine had a small crack ones and it was idling like that.

i did the full version, but didnt block off jackshit because i need all the emissions stuff

teamstealth

where is the PCV?

BoOsTin FD

hose coming from oil filler neck. It has a pcv valve on it. Easy to see.

teamstealth

okay mine has jackshit on that nozzle...which way does the check valve go and where does it go to?

teamstealth

and j/ for the record....how would that cause my car to have a jumpy idle from 2k-2500? just wonderin

teamstealth

nebody?

teamstealth

ok, is this it? if so, which way does it go?

that should run to the oil neck, im assuming if its an oil return line then the part that blows should go to the nipple on the oil neck.

teamstealth

yea found that in the manual and fixed that, and plugged the two most obvious leaks on the UIM (pass. side) but still fucked up...this is startin to **** me off

did you accidentally attach the throttle cable to the wrong err lever I guess??? I really dont know, dont even know if its possible, I dont have my car to look at right now. hehe 3:40 am here,

dubulup

The only time, my car did this is after I finished the full NS conversion...it turned out that I forgot to plug my fans in, BIG OH ****!!!

and it would rev it self 2k - 2.5k...I thought I was really fawked!!!! plugged fans back in and BLAM!

interesting reading about all my problems...hehehe

teamstealth

throttle cable hooked up correctly....and yea i dont think it is possible to hook it on the other "loop thingy" lol. I'll check the fans when i get home 2day, but i doubt i unplugged them. But what it sounds like is ONE messed up electrical connector can cause this funky 2k-2500 rev, so i'll check all the elect. connectors i messed with

teamstealth

*Crosses fingers* god i hope this will be the day i find it.....either that, or it'll be the day of a million start-ups

Are you running on a stock ECU?? I heard they dont work to well with the NS conversion, but thats probably not it. If you have a PFC did you switch its setup from Sequential to Non-Seq.??

teamstealth

stock ECU...yea you have to pull a few strings and trick it into working properly, but many people have done it.

teamstealth

just started it up and let it warm up...checked ALL the places i blocked off vaccuum nipples. LIM, UIM, Y-pipe and i could not feel or hear any vac. leaks
