i have a problem in the morning with my idle. when i first start the car (94 civic w/z6) it revs to like 2200 rpm and idles there. then when i touch the gas and let of it starts to bounce from 1200 rpm to 2500 rpm and back and forth. it does it untill it gets warm then it just idles nromal. any sugestions????? i thought iacv or t/p sensor but not sure which one.

 

if you have a fitv thats it

 

FITV????????

 

Does anyone have any idea what this other guy is talking about?????

 

Fitv=fast idle thermo valve
its under your tb. take it out and shake it, if it rattles take it apart and screw the little white thingy in there.

 

Mine has the same problem, I've done everything else but that FITV. I'm gonna take a look at mine this weekend. If you get to yours before then let us know if that fixes the problem.

 

i will but please do the same

 

erratic idle, i'd say the fast idle valve... but also look for: low coolant, vaccuum leaks... i had the same problem, but took apart the fast idle valve and cleaned and rebuilt haven't had the problem since.

 

had this same problem with my G2 teg...

 

Dumb question I know, Do all hondas have a FITV, if not, what motors are they on.

 

anyone? anyone?

 

OBD1's I'm pretty sure.

 

i took apart the fitv valve and screwed the white ring down and put it back togather now my idle is much better at all times and it fixed the morning problem, thanks again guy.

 

The problem I'm pretty sure as I just fixed it is air in the coolant. Had the same issue when my water pump leaked. Making a air pocket for the IACV. Air in there makes it do that. ONce it heats up it won't be needed any further. Try bleeding your coolant and check for a broken head gasket or water pump that would cause the coolant lose. This fixed my problem by bleeding the system and had to do it every couple of days tell I could fix my water pump delimia.

It's from your IACV. Do you get a temp reading on your gauge even when the heater is blowing cold air? Another good indicator of it.

Try it and let me know I'm pretty sure it's your issue.

 

Doesn't sound like a FIV to me it'd stay that way after Operating temp if that was the case.

 

I thought that the FITV was only used until your car was at the correct operating temp? So why would it affect anything after that??

 

Yeah Why would that make it idle up and down after warm up when these are faulty! I take it that mine is junk because I took it off tonight and **** was rattling inside! I took my f22 throttle body and shook it and i didnt hear the same noise! I hope that this is my problem too! Because just recently my car begain to idle high than bam one day i start it in the morning and high idle.. than it warmed up and the idle begain to go up and down! Please help

But we're talking about a valve that isn't working the way it's supposed to.

 

OK so should they rattle when you take it off and shake it? Im trying to figure out my car too! Im assuming its bad when you can shake the piece and hear it rattle
