Idle problems!!!!!!!!!!!

[Turbodude06]

Ok, so when I start my car in the mornings it idle's high around 1,800 rpms, just like everybody else's car, but once the car warms up the idle goes up a little(2200 rpms) not down to normal like it should, but if I wait till my car warms up and turn the car off and then back on it will idle about what it should anywere from 600 to 1,000 rpms, but usually around a 1,000 rpms which isn't normal I know but its much better then 2,200... Oh and another weird thing if I use my airconditioning before the car is completly warmed up it will just keep kicking on and off and is really anoying.... What Could This Be????????????
:no:

Sounds like an electronic problem to me. But then agian I'm no Honda mechanic.

i have a similar problem with my 93 accord. when i start it it idles around 2k rpms but doesnt drop. i dont let it get to me b/c after a few minutes of driving it usually stops but only lowers to about 1200 rpms. which is still pretty high. i too would like to know the problem

^^^ thank god I don't have exhaust right now cause it would really get annoying then, can anyone help me out PLEASE.....

try that first before you spend any money on parts

[Turbodude06]

^^^ Thanks I'm going to try that tomarrow.....

lol my tps is busted on my hatch so wheni idle it revs to 1600 and drops to 900 over and over for a minute or too and i get some weird looks lol

[Turbodude06]

^^^ LOL I know what u mean, I had a Stealth that did that it was really annoying but mine doesn't surge like that.....


-anOtherh22 I clean all that out and everything and it seemed to help, but I'll see in the morning when my car is really cold.......

[an0therh22]

yeah make sure you tighten that piece on the inside of your fast idle thermo valve.

mines doing the same but it wont stop. and it go's from 1600 to 2500..

Surging is normally a vacuum leak...

[civicracer5000]

check IAV (idle air valve) turn your car on and let it warm, once is warm unplug the connector from the valve and if the car does something like dropping the rpms then the sensor is good, but if it doesn't do anything replace the valve. also check for vaccum leak in your intake manifold

[Turbodude06]

Ok that > http://www.accordinglydone.com/forum/showthread.php?t=13679 didn't work and I've unpluged it and the rpm's do drop so I know its not the sensor so what else could it be?????????????????????????

[civicracer5000]

check for vaccum leak in the manifold

[Turbodude06]

No leaks......

try that, its like the accord thread, but its different, i'm posative it will fix it!

EDIT: wow i can't spell, i meant positive. lol

[Turbodude06]

Thanks I'll try that today and I'll let u know.....

I just did mine this weekend with my LS/vtec. I replaced the IAC valve and then found out that the fast idle valve had unscrewed itself(unscrew the two 8mm bolts,slide the plate off and the vavle just fell out).. i had the same surging idle 1k to 2.5k rpms and then fan kicks on and then idle'd at 1800rpms. but now that fixed..but i thought you was to screw that valve till bottoms out and back it out a 1/4 of a turn and close it up and then adjust your idle air screw.:thinking: hmm well anyways its running fine now.:goodjob:

[SLow_POke]

i seriously doubt its the FITV. seen as it happens when the car is warmed up. . I would lean more on the IAC


sounds liek the throttle sticking also.
have you messed with your adjusting screw?


and the AC issue could be a diff problem

EDIT:: double check ALL your vacc kines

i had the same problem and it still had the jumpy idle after the car was warmed up. it would only do it when i was at a stop. but yeah the FITV situation fixed my problem.
i'm pretty sure it will fix his to...

[optik678]

Have you thrown any check engine lights that can help us diagnose this for you?

^^^ I totally forgot about the adustment screw yea a friend of mine messed with it when I first got my car running cause it was idling funny how do u set those back to normal, I've messed with it a little but it just makes the idle go even higher, right now its screwed all the way in???????

^^^ I wish I had a check engine light then I wouldn't be asking everyone on here, Thanks though.....:goodjob:

[Turbodude06]

anybody have any other ideas, I'm stuck.....

[SLow_POke]

hmm . try this tunr on your car and block the intake passge with your hand. if it shuts off then def not a big enough vacc leak.
if it stays on even barely . you got a leak.

set your adj screw close all the way then back it out about 1 1/2 turn. it will def vary

[Turbodude06]

I know for a fact that thier is no vac leak and I tried that any way and my car died instintly.....
