Idling weird

[jerseyCB7]

When im at a stop light my CB7 idles too low . It always goes from 900RPM then straight down to 200RPM & it like bounces there until i get in gear. What should i do?

[batever]

Did this happen all of a sudden? What's the history.

Does it bounce around 200 and then jump up over ~1500 like it's trying to catch up?

I have the same problem. i have a 91 accord lx. i posted a thread before but not that many people helped me. is it because im new and cb7 members dont even bother to help out the noob lol??

okay guys, it doesnt goto 200, those two tick marks above the solid white line indicate 700 rpms. motor wont even run below 500 rpm.

a couple of things, idle rpm may be too high and the computer is compensating for it. check vacuum leaks and/or backed out base idle screw.

use propane or carb cleaner and listen for the surge in rpm.

i actually bought another idle screw today and put locking threads on it. worked fine. i also took off my throttle body and cleaned it with carb cleaner -. so it did help with the idle issue i have. my car use to idle from 900-1500 or more and was getting worst. But after 2 weeks of playing around and research i finally calmed my cb7. ( but not fixed it completely) a few more days and itll run like new

check the FITV and clean the iacv.

Hey, wed3k
remember you told me to check for the vacuum leaks. Well i did that and i found well actually i just show you.
*Last picture - behind the plenum second line from the top the nipple was completely opened and i plugged it. is it ok?

so you're still having problems? plugging is fine.

[project-CB7]

I'll play around with the idle control and maybe try a temporary FITV and air booster "delete" and see if it helps <==== just found a thread that shows this.

last post by me.

Bleed the cooling system? I heard this can cause idle problems too.

[project-CB7]

do i bleed the coolant when the car is running?

[wed3k]

yes, i believe it is a 12mm by the thermostat housing?
