GZE idle up motor

Well i have been informed that the reason my car wont idle on cold is the fact that my idle up motor on my MAP 4A-GZE is buggered and doesent open and close like it should, so my question is, do i look to buy another one for the gze or is it interchangable with other 4A engines? thanks, chris

is it std ecu
they sometimes get blocked up
but reason yr car might not idle could be air leak
idle ajustin screw screwed in to far
throttle not set right

no, its running a mircotech computer (LTX-8), its definitly the idle up motor. Just want to know if its interchangeable with the part from other 4A engines.

it is interchangeable with either an alloy plate or get a 3SGE throttle body which is bigger and has no idle solenoids.
just hook in a 6mm solenoid after the tb for a cold idle controll. i know it works for me on stock ecu and others aswell

he he..yep..thats that way i did it! mine used to hunt for idle i put the bigger throttle body on..not only did it give it more top end..but quicker response through the whole rev range..i got mine off an AE82 corolla (4afc or 4ac) charcoal canister..the 6mm vaccume solenoid works a charm..hook it up under the throttle body..12v switch..works perfect!

from what i know the idle motor doesnt work on ltx8's
unless its been modified

Thats why it isnt workin in the first place, couldnt get it to run properly, perhaps some mods are needed Chris.

dont waste yr time tryin to get idle motor to work with an mtx8
why do u want it to work
for cold starts or bad idle
for cold starts theres easier ways to get it to work
for bad idle get person to tune it properly
play with timing and mixtures
so many gzes out there with mtx8 and not many have probs

LTX-8, for those confising it with an mtx.
Also, i was only under the impression that i needed a new one due to TRG Automotive (a well respected workshop in this area) advising me so. They said thats the reason im not getting cold starts.. and yes it has an idle problem when warm, like cant decide what revs to sit at, but will still stay alive, unlike when cold.
So as follows, i booked it in for a service/dyno tune/cold start fixing. When i picked it up they told me that the reason for cold start was the idle up motor. I spoke to the mechanic and he clearly specified that the way to fix this problem was to replace this part. As there is a cold start injector not connected, i orginally assumed they might need to connect this for my cold start, but after speaking to him he said that this was only used on the standard ecu. Furthermore it is stated on the printout of what the problems are, that this idle up motor is broken.
So what do i do? Can someone please clarify if this is true "from what i know the idle motor doesnt work on ltx8's"?? And if so what costs am i looking at for 3SGE throttle body + what ever else i need to fix this little problem of mine. Thanks, Chris.

how would a 3sge throttle body fix yr prob
look at how nissans have cold starts
they use a bypass valve
this has nothin to do with the ecu so therefor is easy to hook up
microtewchs are always a pain with cold starts
dont htink you are the first
another thing you can do is if yr aux output is free use it to turn on a solenoid which opens throttle a mm or 2
as for the idle when warm then then that is a tunin problem
get them to adjust timing or some shit
if they play with microtechs alot then they should know
but don tthink it will be as smooth as factory ecu
some cars seam to idle good others idle bit funny
thats just what ive come across
im not tryin to blame or put anyone down but i think maybe the workshop doesnt know alot bout microtechs
from past experience cold start injector is not really needed on any aftermarket ecu
idle motor wil not work on a standard ltx8
so yr best bet is to look at other ways
standard idle motor has 3 wires
12v and 2 signal wires
the ltx8 does not have 2 outputs for the idle motor in standard trim
std idle motor

cold start is easy
just get a auxilary air valve like nissans have run one wire to earth other wire to fuel pump power or ign power
for idle i cant see y they cant get it to idle ok with abit of fine tuning
unless u have vac hoses on wrong

^^ it's that easy?? so i get an auxilary air valve off a nissan engine or am i better off getting a new one? then it will just connect straight onto where the idle up motor goes?? or somewhere else. Sorry bout all the questions, just dont have much of an idea about this at all. Thanks for all ur help so far anyway man, Chris.

yeah, but ive been doing this for months, well not really, i drive off and keep my foot on the gas a bit when i have to stop. Its getting quite annoying considering i drive my car everyday and quite frequently, to uni, it cools dowm, to home, cools down, to work, cools down, back home. So it gets annoying. But u think this is to much of a hassle to bother? Hould it be easier getting another idle up motor and getting it hooked up to the microtech?

as drift86levin and i have both done is the best way to do this its exactly the same principle as the nissan bypass but with an output from your ecu linked to engine temperature to switch it..easy..
the airflow supplied by the 6mm solenoid from an AE82 charcoal canister allows it to sit at a happy 13-1400rpm cold
as for the TB bigger is better!

sort of correct , idle motors work perfectly on LTX8's with the GZE coil packs, every GZE (and most toyota's, nissan, subaru etc) i do uses the idle motor,
you just need to order the ecu with idle control, you use the 2 spare ign outputs for this, it works in closed loop as well so just set the rpm you want it to idle at and set the min and max openings and your done, if your ecu dosent have this and you have the gze coils send it to microtech and ask for the idle control to be put on it, it really helps with cold start just set the idle up amount and it will idle up nicely when cold,
if you have a FMIC on the gze that can be half the idle problems, make sure you have no air leaks in the core or it will never idle, a lot of these cheap import intercoolers leak air and cause a lot of problems,
if there are no air leaks it is tuning,

hey dale thats good to know
if i ever order some microtechs for 4ags ill ask questions like that first
its a pity some people dont research enough what customer wants
to then get right ecu

it is a pity, i always ask the questions like that before ordering,
the only the 86 and 100kw dont use a idle air valve but the gze and 20v's do, ep91 starlet does etc, its not hard to give the customer a car that does everything like factory!
