Carburator idleing problem

My 1989 isuzu 2.3 liter truck will not idle. When the engine gets below around 1200 rpm the engine just shuts off. The truck runs fine otherwise with no loss of power once I get the rpms up. It is a carburator not fuel injected. Any ideas?

Idles@2500 rpm until engine warms up


old post
all do, everyone. but. the devil really is in the details with EFI.
this IAC valve does that,
to speed it up warm up , put in a 195F thermostat.
this assumes 800 RPM is hot.
most of these engines, do this. new. bewlow.

1: cold start, for 3 to 15sec, 2500 rpm , worse in alaska.
2: then the above DASH pot closes and IAC takes over, at ~1200
3: then as engine heats the IAC closed inch by micro inch a
its now 100% closed and the ECU not controls idle hot.
using the modulated ISC,
there is a fast idle feature on this year, 950 to1000 rpm hot
with these turned on.
1. headlights hot.
2: defrost glass, rear.
3: heater fan on.
4: a/c on if opted.
other wise 800 is normal hot.

What should the idle speed be set at on a 1989 jeep wrangler 4.2 liter straight 6 cyl. It has a 2bbl carb. It idles at 1000 rpm right now but seems fast or is that about right?


Most carb. engines should idle between 725 and 750 R.P.M., lower the idle and be sure to check the timing. You should have an emissions label under the hood to explain the idle and timing.

4.0 liter motor will not idle below 24500 rpm. 1994 aerostar, 4 liter motor, auto


i hope that the 24,500 RPM is a miss-print and you mean 2450 RPM.

get a can of carburetor cleaner and spray around the intake manifold with the engine running if there is a vacuum leak causing the idle problem when you spray the cleaner around the leak the idle will change, if you find no leaks replace the idle control valve or motor witch ever you want to call it.

let me know if there is any thing else you need.
