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?

I have 1990 ford f150 5.8 liter it idles high when in park and idles about 1200 rpm when in gear and sometimes surges up and down. i have clean the idle control and check showing 12.5 ohms still won&#


One common problem is a vac leak or a sticking throttle plate.
The computer controls idle speed by how much air is allowed into the intake. The idle control valve could be sticking even tho you have cleaned it, or have a faulty motor.

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.
