i did my b16 swap in my 89 hatch and it idles fine when cold but when it gets to operating temperature then i get a fluctuating idle, help? thanks a lot

 

TTT

 

any codes? Perhaps IAT

 

fluctuating how? 800 to 2000 to 800 or 800 to 200 to 800.

 

i took off the ait and clean it, nothing, changed it, nothing
fluctuating like 1000-2100

 

sounds like the fitv came lose

DEF

 

fitv? im a n00b

 

wow i just researched it and then it sounds like my problem, when i get home i am going to give that a try, thanks a lot, honda tech pwnz all

 

also check for vac leaks..

 

if you need more help than that let me know i just fixed that problem on my friends car. The pictures under 123 fitv or whatever dont work no more but i can walk you through it if you need help

yeah i was looking for vacuum leaks but couldnt find any and i also followed a vacuum line diagram for the b16

 

hey deftones was that the problem with his car??

yeah his fitv had fallen out because it became unscrewed...its underneath the throttle body on his car. his name is hondaguyef if you want to talk to either of us. But he just had a kid last night so he is at hospital with his wife. Also im not sure why it becomes unscrewed over time but it does so check that out...maybe yours hasnt fallen alway out and probably needs to just be tightened back in.

hmm do u have any pics of what it looks like

 

dammit, took it off and it looked fine

 

ok i fixed the fitv and at cold there is no erratic idle and the idle is good but when warm it the fluctuating idle starts up...

 

what is your idle at when it starts up? Maybe you just need to turn it down a bit?

DEF

 

the idle is 2000 at start up

 

well than, lol, turned out that my throttle body gasket was **** and torn, thx a million for the help guys

 

My civ does the same thing too it idles up high and goes up and down only when warm. hmmm I wonder if I should check my tb gasket as well.
