FLAWLES Posted February 25, 2009 Share Posted February 25, 2009 this is post 84 so ban if you want just done a engine tranplant into my chaser runs mint bar the 4000rpm idle. i think its the idle up valve but am really un sure mine seams to be jammed open i think, ( assuming that when the soleniod is up its open and when its down its closed ) is this a comin thing on 1jzgte? if not anyone got ideas? have thought about bashing shit to get it freed up, but been advised not to do this also have been told to seal it shut as you dont really need it? spence/sam true or false Quote Link to comment Share on other sites More sharing options...
fuel Posted February 25, 2009 Share Posted February 25, 2009 there's no vac leaks in the inlet manifold? throttle plate is definitely closing properly? I don't think an idle valve is going to let through enough air for it to idle at 4000rpm surely? You could try blocking it off and see if the idle speed drops down.

FLAWLES Posted February 25, 2009 Author Share Posted February 25, 2009 yea check all things t-cable ( we took it off ) found one leak but fixed that there is one thing that we didnt check, and that was the vaccum hose to the stearing rack ( so i have been told ) and the port size on the valve is big man oh and the valve is the same as the twin turbo 1jz Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 25, 2009 Share Posted February 25, 2009 mike said last night the ISC is jammed wide open obviously this is going to cause it to idle spaz did he not tell you this? Quote Link to comment Share on other sites More sharing options...
FLAWLES Posted February 25, 2009 Author Share Posted February 25, 2009 you can be brash at times i was standing over him ( not that hard ) and helping along with LT dan= mega sweet waikato toyota cunt but what i want to know is A) can you fix the old ones can you loan me one........being checky i know but dont care at this point in time, want/need car going C) can you block up the hole in the mani and carry on as if everything is fine, with out any issues poping up?

Spencer Posted February 25, 2009 Share Posted February 25, 2009 Yea bro just being a dick because you were beating around the bush in your post, a) Yup you can but depends whats wrong if the stepper motor is fucked then no, They usually just get stuck because the motor has been sitting around for fucking ages proably can loan one if we get a working one back eventually (Presuming ours is a good worker) c) Blocking the hole and just turning up the idle screw is an option just to get it going but you loose your cold start idle up function and all other idle ups AC, lights, etc Quote Link to comment Share on other sites More sharing options...
thegreatestben Posted February 25, 2009 Share Posted February 25, 2009 My 1ggte had the blocked ISCV. To check it we put a pair of vice grips on the hose, and wound them up or down to change the idle. We pulled the valve apart and gave it a good dousing with WD40/556. Came right, but not all are salvagable. Quote Link to comment Share on other sites More sharing options...
FLAWLES Posted February 25, 2009 Author Share Posted February 25, 2009 ha no worrys bro still heeps of love for you yea your first post got me all mad so i went down to the work shop drilled some small arse holes through the alley with a jet drill due to the small gay roll pins holding the motor on. whipped one roll pin out had to stop due to phnes ringing and work dutys etc they do look like there servicable so i spose thats good in a sense, will let you know how it pans out in the next few hours Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 25, 2009 Share Posted February 25, 2009 ^ nothing like getting pissed off to get some action happening let me know if you want to use our one Quote Link to comment Share on other sites More sharing options...
corrupt Posted February 25, 2009 Share Posted February 25, 2009 My flatmate just done the same/similar conversion to his chaser 1jzge -> 1jzgte and had the same 4000rpm idle issue, but did solve it in the end. Ill find out what he done. Quote Link to comment Share on other sites More sharing options...
corrupt Posted February 25, 2009 Share Posted February 25, 2009 I asked my flatmate, he said his electronic idle sensor was broken, so he blocked it off at the plenum and then adjusted the idle via the throttle butterfly. Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 25, 2009 Share Posted February 25, 2009 ^ yea thats his issue basically engines that come from japan (or sometimes NZ) sit around for ages. The oil and crap from the blow by sits around in the inlet and idle valve and goes rock hard ususally a saok in some solvent and abit of persuasion and they work again. Unless the motors are fried Quote Link to comment Share on other sites More sharing options...
FLAWLES Posted February 25, 2009 Author Share Posted February 25, 2009 whipped it all apart looks like the motor is fried spence do you know if the motor winds the plunger out or does it push it out? Quote Link to comment Share on other sites More sharing options...
thegreatestben Posted February 26, 2009 Share Posted February 26, 2009 Not sure If I'm answering your question right but the one on the 1 g had six pins on the plug. you'd put power across the pins in a certain sequence to get it to move in or out. I can show you in the page in the manual later if this sounds like the same set up? Quote Link to comment Share on other sites More sharing options...
mikuni Posted February 26, 2009 Share Posted February 26, 2009 A stepper motor. I think what jareds asking is does the motor open the valve or close it and what the normal position is? Or some shit.. Quote Link to comment Share on other sites More sharing options...
FLAWLES Posted February 26, 2009 Author Share Posted February 26, 2009 yea sorry trying to explane stuff while on the phone to a customer isnt the easyest what i meant was does the stepper motor rotate the plunger to shut it and open it or does it push it open and close reason i ask is i dont want to go prying anything the wrong way etc make sense????

Spencer Posted February 26, 2009 Share Posted February 26, 2009 yea stepper motor rotates the valve in increments dude Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 26, 2009 Share Posted February 26, 2009 best bet is not to force it just clean it learn how it works and try putting voltage to points and make it move if it wont the stepper motors fucked. Clean it in some light solvent first though. Its not a major block it off until you find one and wind out the idle stop screw it is not a big deal Quote Link to comment Share on other sites More sharing options...
FLAWLES Posted February 26, 2009 Author Share Posted February 26, 2009 i was looking at doing that just winding out the plunger till it sits on the seat and seals up motor isnt bugared once again i jumped to that conclusion, wants to move, but the shaft is a bit rusty i think i will let the motor sit in some crc/inox etc over the weekend and see we that gets us sam was kind enough to lend me his one for a short amount of time which is top notch Quote Link to comment Share on other sites More sharing options...
escortman Posted March 4, 2009 Share Posted March 4, 2009 I asked my flatmate, he said his electronic idle sensor was broken, so he blocked it off at the plenum and then adjusted the idle via the throttle butterfly. yeh we blockd the sensor off and joined the pipes then adjust idle from on teh throttle body runs sweet Quote Link to comment Share on other sites More sharing options...
