Idle problem

[newbyyy]

I have 97 civic hatch dx and it's idling from 2000 to almost 3000 non stop I cleaned the sensors and the throttle body but it got even worse than it was....any ideas on what it could be

[Rocker]

Tps sensor or cold start valve

[ct tibby]

actually sounds like a vaccum leak. possibly a iac. do you have a vac gauge?

[newbyyy]

Well I replaced the iac so it can't be that but I'll try the tps and no I don't have a vac gauge I also changed the map sensor and replaced hoses that were bad. It still doing it

[efadict23]

yeh well fist is there a cel? if so find out wut the code its throwing cus that would be your problem....a code should come on for any of the sensors that these guys mentioned..including tps...iac...and map sensor. now if you dont have a cel then in all likely hood its the cold start valve thats sits under the throttle body opening...the reason for this is that there is coolant flowing through it but if you notice there are no electrical connections to it! it connects directly to the iac so if its clogged or broken it will slow the flow to the iac and make it do wut its doing without throwing a code....you can just replace it and this part is the same on singles and duals u just have to switch the lil cap where the hose connects....or if you cant get one try takin it off unscrew the end where its flat with two tiny screws and you will see that its spring loaded...if the spring is all the way out then u found the problem..take a screw driver and tighten the spring back down....try these two things and hit me in the mornin...lol doctor efadict does it again!!! lmao

real simple, start the car, spray carb cleaner over all possible vacuum leaks. When the engine idles down, you have found it.

if the iac is stuck, plug the whole on the inside of the tb with ur finger, idle should drop to 8-1000 rpm

[newbyyy]

Ight imma try both cause it has no code just bad idle imma deff try that and get back to u guys thanks

[game2o3]

if u cant fix it sell it to me!! lol , gl tho!

[newbyyy]

I'm selling it after winter just trying to fix the idle problem

[Jovanni91Da]

deff try your tps bro

[ct tibby]

is ur throttle cable to tight?? lol

[newbyyy]

Imma try everything today and get back to y'all if it's still doing it

[newbyyy]

So I tried the cold start valve and that didn't work so today imma swap the tps

[PH3R33L]

What kind of throttle body because i just changed my boys throttle body and adjusted the sensor to .5 volts and now it runs great.it was doing the same thing that yours is doing also try the carb cleaner trick

[newbyyy]

I got a carbuerated intake Mani so my throttle body sits up top I'm going to change the tps I haven't done that yet
