Hey when ever I turn on my lights, turn up the volume on my CD player, use the fan, or use the windshield wipers my idle will jump around. It does not effect me when I'm driving but if I come to a stop the idle will fall and the raise. It just plain annoying more then anything. I have heard it could be my idle control valve and that I need to clean it. If so...how do I do that? And where is it? Do I need to know anything ahead of time so I dont damage it?

If you think its something else...please share your mind!

Thanks

 

does it JUMP, or does it slightly rise and fall?

your IACV/FITV could need a cleaning

check your battery/alternator/GROUNDS first, though.

 

Your iacv is located on the back of your intake manifold and is held on with two 12mm bolts. Unplug it first before you take it off. Go to advance or auto zone and pick up a can of Brake Parts Cleaner, or equivalant. Once you have the iacv off, spray it down on the inside where the two ports are and make sure you get all the black gunk out of it. Once your done, just let it sit and dry off before you put it back on.

 

heres how to clean the iacv, https://honda-tech.com/zerothread?id=1564019 . If it does it when its cold it probably the fitv, warm then the iacv.

 

thanks guys I'll try that

 

That link was for the FITV. 96 and older cars just have the iacv i think. Here is a link on how to locate and clean the iacv https://honda-tech.com/zerothread?id=1575913 .

 

just took it off and cleaned it. Helped some but still the same problem. Maybe I didnt clean it good enough? I dunnno it looked clean enough...ahhh this is bugging me

 

dont know if this will help but...when I start my car before its been warmed up it idles high around 2 but then once its warm it drops, i think thats normal, but when I start my car after its already warmed up the idle jumps around till I get on the gas and move...then its fine...also when I beat on it the idle seems to jump around alittle when im stopped.

 

bump

 

What Civic year and engine is this?

 

i have a similar problem. I havent replaced my iacv yet, mine only freaks out once the engine is hot. could be the same thing.

 

hey yea i have tha same problem but it happens when my car is already hot maybe after an hour of driving it wont hold tha idle and need to step on the gas wat do u think it could be its a
mini-me vtec would
appreciate some feed back

Anyone have any clue whats going on?

 

Have you ruled out a vacuum leak?

 

no...how do you check for that?

 

vaccum leak tester. Hooks onto your vaccum system, and whistles if u have a leak

 

if it only jumps when you turn up your cd player, or turn on lights etc. things that require more electricity, wouldnt it be something to do with your battery or alternator rather than iacv?

 

i dunno...like I said it also does it does it after I get on it for a while...or when I start up the car after its already warm (as soon as I put it in gear and drive a bit it stops)
