Do the following to clean the intake, this should help with the rich run. Also change the oil, it will be full of fuel.
Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional

check for vacuum leaks especially around the intake manifold gasket. Although the engine appears to be running rich, it could also be misfiring due to being too lean in one cylinder. When the cylinder doesn't fire the charge, it goes into the exhaust completely unburned and looks like a rich running condition due to the unburned fuel. If it is a vacuum leak causing the problem, the engine will run fine at road speeds but misfire at idle and not pass smog.

SOURCE: truck stalls

if it is burning rich, there for it will be over fueling around low rpm i do belive, which will cause the engine to flood, im guessing after you have been low rpm then go for high rpms, it like hesitaes and takes abit of a cough then goes, if that is the case then it is overfueling.

there is a way to advance/****** the engine mixture, but id say for safe if you don't know what your doing to take it do a garage, and ask for it to be timed up with the timing strobe light :) which will stop the, over fuelling around low rpms.

Idle up and down is an IAC motor, or a vacuum leak.

I have a 1999 jeep wrangler/Sahara. It starts up fine then stalls. No idle.

Dear Lori,
is this a request to gue$$, or to test?
i can list 50 reasons to cause stalls.
it's a huge list. (have it)
or how to test it?
no engine stated, there are 2?

The engine stalls, if the engines is ok (if not, lots more)

bad fuel.
lost 12vdc power to the injection system or spark. (see lamp dim)
ASD relay logic (PCM) saw an error (scan it) and the ASD dropped out.
bad spark , not getting a tune up this decade???????
bad fueling, too rich (floods) or too lean it stalls.
EGR stuck open.
lack of air, to engine , clogged air cleaner or ISC stuck closed.

there are simple tests for each
why not get it serviced,?

Driving car and car stalls while running

Haynes manual shows this for that problem, but please take it with a grain of salt and dash of peper:

1. Idle speed incorrect
2. Fuel filter clogged or water and impurities in fuel system
3. Distributor components damp or damaged
4. Faulty emissions system component (talk about vague :)
5. Faulty or incorrectly gapped spark plugs
6. Faulyt spark plug wires
7. Vacuum leak in intake manifold or vacuum hoses
8. Valve clearances incorrectly set

That last one is possible IF the new timing chain/belt was installed a tooth off.

All info is from a Geo Metro/Sprint Manual, but it may help.
