Hey guys I've been having this problem with my b16a with the idle just bouncing up and down fast and sometimes dying.This only happens when the motor is cold, it runs perfectly fine when when it's warm and also starting starting it up when warm. It don't bounce while driving just when it's a cold start idling. If anyone might know what it can be please help any help will be appreciated(:

also I don't have any check engine lights

 

Some good stuff in here. https://honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/b16-wont-hold-idle-keeps-stalling-551851/

 

Mines different mine just happens when I first start it up In the morning the rpms will be steady at 1500 then will jump to towards 3000 than drop to 500 really quick for like 15 seconds or after it goes away it idles fine back to 1500 then idle at 800 or so when warm. The rpms won't jump when I'm driving only on a cold start.

 

The troubleshooting steps are the same.

FITV, IACV, vacuum lines.

Fix those first, then come back and post your results.

 

Have you cleaned your IACV and checked vacuum lines?

 

I have not cleaned the Iacv yet but will in the morning hopefully that can be it. As for air leaks I don't think I have since I checked all the lines when the cruise control plug from behind the intake manifold came off a couple months ago.

 

I agree with the above posters, check for vacuum leaks and your IACV. Maybe even your MAF?

 

First off, whats the year/make/model of your car? Was the b16 swapped in?

 

It's a 98 civic lx with a 92 b16a swap with just the regular i/h/e

 

Update I just discovered a sqeaking noise coming from my distributor this morning. Also the rpms did jump also turned on like normal. Also if feels like it can be my distributor because I've had problems with my old one with the same effects but didn't think it could be this one since it's pretty new

 

What do your contacts look like?

 

If the idle bounces like it does while the engine is cold, it points to an issue with your FITV. Clean it, and see if the problem persists.

If your distributor is squeaking, or squealing... I believe the bearing inside the distributor may be going bad.

 

check for leaks

 

The distributor does have a small leak I'm going to fix that and also ima try to post a video how the rpm jump. Thanks for all your guys help(:

 

Here is a video I posted on YouTube on the problem I'm having with my car.

 

When do you plan to attempt the troubleshooting steps we've given you?

 

Today im going to work on the distributor cleaning up the cap and rotor I'm really not going towards the fitv nor Iacv yet because it don't seem like it can be that.

 

Cleaning it will not do much, unless there is some sort of corrosion. If it has a lot of corrosion, or if it is burnt on the rotor and cap, just replace them.

If anything, it may cause a miss fire, or poor performance issues. Not a hunting idle while the engine is cold.

Plus, if you're removing the distributor to fix an oil leak, be sure to mark where the distributor was at, or you can also re-do the ignition timing.

Good luck on your hunt.

 

Holy ****** ****, someone report this to the mods. We got another ignorant (fill in blank) refusing to take technical advice and rolling with it.

 

Update cleaned out throttle body, iacv and distributor. Distributor was full of black powdery stuff also contacts were pretty burnt so I sanded the burnt off. The rpms still jump but not as crazy only a twitch now

 

You're dancing around the one giving you the issue.

By the way... it sounds like your distributor is beginning to fail.

 

Yeah ima swap it out since I have warranty on it
