okay.. here is my problem. I have a 2000 honda civic si. i just took off my turbo kit to become na. I just realized that when i start my car it revvs at about 800, but when it warms up it drops to like 100 and sometimes my car stalls. I cleaned out the iacv and also adjusted the throttle screw. I even checked throttle cable and everything is fine. someone says that it might be a faulty iacv.
Anyone else think this is the problem.
any help will be appreciated.

 

well what did you have on there and what did you take off?

 

i had a full turbo kit. turbo manifold, ic piping, ic, blow off valve, wastegate.
replaced with a dc 4-1 header and injen cold air intake. that's it.
i saw that i had a vaccuum leak. the line from my manifold to cruise control was cracked. so i replaced it. now i have low idle.

 

okay.. today i cleaned out the iacv. still did not help out. i bled the radiator for bubbles. slight improvement, idle is set at 800, but when i rev, it drops to 100-200, then back to 800. i ordered a new iacv, maybe this will help.

 

looks like the iacv is not catching the idle fast enought..
if you already cleaned it then replace it..
if you are have problems stalling leave one of the vacuum lines (small ones) off..

it will get the extra air it need to not kill.. it will idle higher tho

 

why not adjust the idle to compensate?

that does not work for this problem.. idle drops too fast and the little extra air for the idle screw will not keep it for stalling

hmm...just a thought, never really delt with turbo's, just a process of elimination.

 

yeah... that's what i did. i have been running with the vac line off of cruise control...so that's why it idles high... good so the iacv is my problem..
thanks

 

WTF.... Okay now im trippin........ i changed out the iacv and it still idles funny...
now my car seems like its gonna ide even with one of the small vac lines disconnected....when the car sits for awhile it seems okay, its when i accelerate then let go, it will drop almost down to 0...

Please someone help... i dont know what else to do...
maybe tps... damn..
