Algiht, Im throwing CEL 14, IAC, and my idle is fucked up when cold, the car jumps between 1500-1700 rpm, but when it warms up its fine!!!! But when i hold the throttle steady at 1500 rpm when warm, the idle hunts again, I have no vacum leaks, and I have tried 3 different IAC( dont know if they all were good), damn it can anyone help???

u should check your valves. what engine is it??? i have a same problem, after i loose the valves a bit, it's stop. try that and let me know

 

Well i dont think its valves, but ill check them, also replaced ECU with my stock CX ECU and the problem is still there just no so bad, I am beginning to wonder if it is a tps problem, cause with the CX ECU it only does it when given very little gas, like if driving around and the rpm is at 1500 and i give it full throttle in like 5th its fine, but if i try and give it jsut a little gas the car starts bucking and ****....

Im going to try and trouble shoot some more.....

What about the FITV?

 

mine has this problem and also i bought this 92 civic dx with lx engine and it idles at 17 then 20 then 15 then 20 then 17 then 20 and so on but when you put it in drive or any gear it quits...... whats the deal

 

I would say check that. I have helped a friend who had a hunting idle and sure enough it was a FITV (fast idle thermo valve).

 

Yeah I check the TPS and its good, I heard you can disable the FITV, I did it on my old motor, but my new TB doesnt have the place to remove it, can i jsut unplug the coolant lines???? How can I disable that POS?? Also if i hold my finger over the small hole in the TB, it idles fine, WTF???

The FITV isn't on the TB. It is there to allow air into the IM when the car is cold at idle. It probably isn't working correctly and is causing your problem.

 

what kind of motor is this? Is this a swap? I'm having the same problem with my LS swap. Do all honda motors have the FITV? I see the IAC but have yet to see the FITV.

 

im in the same boat as you, i got a code 14 and have changed the IAC 4.. no 5 times now with used IACs. now i have the code gone but my car still idles all messed up. it jumps from 1500-3000 when warming up and then when its warm it idles between 1400-1700. did you bleed the air out of the coolant? air in the coolant will make the idle jump around. i hope to try this out today.
good luck

Ah its just a d16y8 motor, but damn it i cant find the FITV!!!!

HELP!!!!!

Jesse

 

Should be on the bottom side of the throttle body!!

 

is there a FITV on a b18b1? Cause I don't see anything like that on my manifold. so what could cause my idle problems?

 

Yeah thats where I've always seen them.....

 

ok, so I don't have one
