Normal idle for a b18 is around 1100 rpm's correct? In my sol I've noticed that when idling, the rpm's are dropping to around 800 and what even looks like 500 rpm's. I didn't think that was possible without the vehicle stalling out. Advice?

 

:wavey: anyone? :happysad:

 

B18A/B/C idle is the standard 750 +/-50 RPM.

I doubt a constant 500 is possible in most I4 piston engines, however it can "bounce" there. If it does somehow hold a 500RPM idle, it'll shake like hell.

Sounds like an IACV (EACV) problem.

 

my integra b18b1 holds at 500, doesnt shake, and i know the tach is correct.
I've been looking for help/ideas cause i know it's not right
also my problem is not the iacv . if you got anything let me know

 

1100 is too high, man! You definitely want it down near 700-800.

I also agree with Kai - sounds like an IACV issue.

 

is there any cons to having a high idle? my idle is ~1300, and should be 750-800 or so, but i dont mind it because i'd prefer it a lil bit higher in these cold ass winters.

btw, what other possible causes are there for this behavior? i might want to fix my idle after the winter

 

Increased engine wear, but not much.

Possible causes, IACV problem, or some sort of small vac leak.

 

Minor correction: idle spec for all B-series VTEC motors is 800 +/- 50 RPM.

Anyway, this could be an IACV or possibly a fast idle thermo valve. Depends on when exactly your idle is acting funky. Does it do it when the engine is cold, warm, or all the time?

 

my 99 b18c1 idles at around 500-600 actually and it seems fine..
