i have a EK and my engine is throwing code 14
my idle is funky, it goes upto 1500 then bounces back to a grand cause i think its like the ecu is governing the idle to 1500...so i wanted to check if this was it so i changed the idle setting to about 3000 rpm, and i was right, it goe supto 3000 at first then it drops to 1500..but weirdly it goes back up to 3000 in a few minutes...
i pulled the tps plug and the idle was fine, none of the pulsing at 1500rpms...but ofcourse cant rev past 3000

the work i did is..
i swapped in a worked itr bottom end, a gsr head, im using the gsr ecu
i also swapped from automatic to manual

man i want to get this done
any help would be awesome... please!

notes that might help:
1. for some reason my heating doesnt work anymore..i cant even move my little temp setting to the right anymore...it just bounces back to about 2/3 to the right
2. when im really on the gas, like gunning it at 6 and 7 grand, and i just drop it in neutral, the car sometimes dies, or just goes down to like 100rpm about to die, sometimes comes back up, sometimes stalls.. but i think thats the fuel pump, my friend has same problem and walboro 255 fixed it up right...

please help!

 

your "funky" idle could be caused by something as simple as air bubbles in your coolant or a dirty iacv...as far as the stalling i would try upgrading your fuel pump

You zip tied something doing electronics trying to hide the wires...
Or a wire running inbetween the control lines/levers.... Been there...

thats sound like its most likely the cause of that problem

 

zipties are mybest friends haha...
now that i think about i had to remove my console to replace my boot, i guess something got lodged there while i was putting the console back...thanks... now for the mor eimportant problem..the idle (:

would a bubble in the coolant cause my engine to throw the code?

 

my car sometimes does that weird idle thing, but i just rev on it and it stops....lol, quick fix...and yes, definatly upgrade your fuel pump

 

my idle is everytime im in neutral...i cant just rev on it and fix it...

 

and yes i will upgrade my fuel pump

 

I believe a code 14 is for iacv so either its a bad wire, bad iacv, or dirty iacv.

Yep. Can't believe no one said that before you..

 

i just cleaned my iacv yesterday because i had funky idle
problem solved

 

how do i get to the iacv?
do i have to remove the intake?
i can BARELY get to the tps sensor plug, but i dont see the iacv, is there a tutorial anywhere?

 

also, did you have the cel before u cleaned the iacv? and it dissapeared afterwards?

 

have un pluggen anything lately in or around the manifold

 

no, I had no cel, just a surging idle

the iacv is on the back of the intake manifold
it has a black cylider on the side of it and has 2 coolant hoses as well.
connected w/ 2 bolts
(at least this is all true on my y8)

 

well i have a cel, so im thnking it might not just be dirty?

pdiggity: do i have to remove the intake manifold to get to it? or can i reach around? or is it easier to go at it from under the car

 

its right on the backof your IM. 2 12mm bolts and 2 coolant hoses.

 

am i looking at the wrong place? i cant find anything

 

right on the back man, its like a little cylinder with coolant lines going to it. its the only thing back there with coolant lines on it and a harness plug on it.

 

i feel like a retard cause i cant find it, and its really cold outside too, does anyone have a picture?

 

number 9

 

wow your awesome, man i cant even get to it, are my hands and arms that fat? i cant even unplug the tps plug without thing and long pliers

what should i use to clean it? distributor cleaner?

 

carb cleaner

 

im sure this will help my idle
but like the other guy said, he didnt even have a cel
is there anything else that could be giving me this cel and idle?

im going to clean it first thing tuesday morning (supposed to be warmer)

 

your cel could be caused by your fuel pump problem, have you checked the code yet?
