idle problem

[johnm]

hey wussup im new here and i kno every1 had a problem like meh cuz most accords my RPM goes up n down up n down. i was reading some stuff in here n one guy said all he did was change da pcv valve so i changed dat but it dint do nuttin i think its da IAC valve but dats too expensive if i go buy it aite i hope some1 can b helpful thanks.

heh I see your from the deep southwest, but DAYUMN is that a heavy accent.

Are you getting any Check Engine Lights? You may want to clean out your fuel filter and check that the fuel pump is functioning properly. Is it a new problem that just started, or has it always been an issue since you got the car (or did you just get the car)?

Also, is it really cold there? Our engines cope with low temperatures by revving higher than normal then they go down later.. is this an always present issue or just sometimes?

Try to explain in more detail what the problem is, and although I'm a picky jackass.... try to make it more legible please, more periods and real words never hurt anyone. :)

Alright, that was mean, but I had to read that written word very slow. Anyway, have you ran codes on your car yet? That will tell you anything that is wrong that has a freakin sensor on it. (Pretty much everything) If you don't know how to run your codes, I'll explain. but just in case you do I'm not typing all that shit unless you need to know. But to me what it sounds like is a vaccum leak.

[TheFirstNutZo]

yeah sorry that I came off heavy like that but I get bugged easily about that kind of stuff.

nah i dont kno how to check da codes. how do i do dat? if its one of the vacume lines do u kno which ones dey can be? aite thanks

[johnm]

can ane1 HELPPPPP pleasee haha cus dat shit is gettin annoying now RPM goin up n down up n down b4 it the engine heats up. or yall think its just da weather? cuz when it started gettin cold up here it started doin dat shit so ionno ANE1 HAVE ANY SUGGESTIONS? aite thanks

[TheFirstNutZo]

yeah well our engines run as low of an RPM as they can, and when they start to stall they revv up, so you can get a fluctuation between 1-2 Krpm that can sound somewhat strange until the engine heats up. Inside your car, when you are sitting in the car, look at the intrument panel. the CEL (Check Engine Light) HOPEFULLY doesn't light up at all. If it is lit up, or is blinking, refer to a repair manual to see what the code is (series of blinks). There is probably one laying around on the internet somewhere.

[johnm]

nah engine lite doesnt come on

[Repeat99]

In your kick panel on the passenger side, you can look right in there and see a blue wire clip thing with 2 holes in it. What you want to do is take like a paperclip and puone end into one side and the other end of the paperclip into the other, completeing the circut. Then, turn the key to the ON position, do not turn the engine over. Just so that the radio would come on. Next start counting how many times the engine light blinks. When it pauses thats when it will either run the same code again or start giving you a new code. After that refer to a repair manual to see what the numbers say is wrong with your car. Now as for if it is a vaccum leak. I would first check the air intake vaccum.

mann i drove my car today and da RPM goes up n down all da time now b4 its just does it to warm up da engine but now it does it whenver i put it on nuetral on da stop light or somthing man dis shit pissin meh off. yall think i should just go to a shop n do a diagnostic test to it? i kno some1 does it for 50 but ionno im kinda broke haha dammm i needa get dis shit fix HELPPP PLEASSEE

tonight (its about 10 degrees) my engine wouldn't stay running unless I manually kept the RPM above about 2000. earlier today it was about 25 degrees and it was bouncing between about 1000-2500 RPM. The cold weather is hell on our engines.

To get it to stay running tonight, I just held the RPM (in neutral) at 5000 rpm for a few minutes until the engine got good and warmed up, then it was okay. try something like that and just make sure that its not the weather fucking with your engine. It could also be a screwed up fuel filter or air filter. My brother got a clogged fuel filter the other day and his car kept dying on him after revving up and down a bit.

[johnm]

is it hard to replace the fuel filter? cuz i never done it. if i take out the fuel filter is der gonna b like gas in it? do u kno ane site dat has a instruction on puttin one on? thanks

[TheFirstNutZo]

no, I don't :( we fixed my brothers' problem by filling the tank all the way up and then parking it on a hill for a day, and all of the crap settled to the opposite end of the tank.

[ridin90accord]

you8 just take off the little black box where all the vacuum lines run in to... and right under it is the fuel filter.. then you go to he fuel rail and there is a little bolt that looks like it is for nothing, loosen it(its the fuel pessure release)...then you just un bolt the fuel filter and put the new one on... tighten down that bolt and put everything back together and your done... pretty quick and easy job

[ridin90accord]

hint... make sure you have a rag around.. a little gas will probably come out.. nothing significant.. but just might as well keep your engine as clean as possible

[johnm]

say riddin90accord have u had da same problem too? do u think its really the fuel filter? or somthing else? and FIRSTNARRUTO did u had da same problem too? cuz dis shit is really anoying now man its doin it all da damm time.

[halfros honda]

yeh cold is no fun i let my accord warm up every mornin for about 10-15 mins it's start idle is around 2-2500 k rpm then it finally settles down once warm, anyway whens the last time u had a tune up? my car used to run weird when i first got it n used 2 shift hard so i changed the tranny fluid problem solved engine problems were solved by routine maintenance (tuneup) as far as a vacuum leak problem i'm not sure, maybe a bad idle speed sensor. good luck wish i could b more help bro'

[92BLACKEX]

dude it is a vacume leak, it's happend to me a bunch of times, you say it doesnt do it when you just started it, so it's idleing high, then when the engine heats up the ecu wants to drop the idle, so your proply getting a leak which alows air in that the computer doenst know about so it jumps rpms, try running the engine, and listen for wistling. If you can't find anything.... Get throttle body cleaner, and spray it where air can get in( by gaskets, throttle body, manifold stuf like that) you'll know when you find it. also try resetting the computer, it might, might work but thats all i can think of

[AccordTunr333]

I had the same problem, for me it was the throttle body...I picked up a used one, bolted it on, and it was gone. It was something internal that rattled when you shook it. No problems and it's been about a year.
