You forgot to say car model name, , or year.
Always state car exact type, and year, first.
but starting in 1989 1.6L all have EFI. no carbs.
1989 1.3L had carb.
EFI , has no physical choke at all.
EFI , measures the air and coolant temperatures. and adjusts fueling
by those metrics, and others. (&barometics)

It was a much easier adjustment in the "old" days. I would have a trained tech adjust it.

SOURCE: ford mondeo mk3, intermitent dumping of water from

You may have an air pocket in your system which some times happens.  One way to get rid of it is to take the upper hose off on the engine side,  fill your system with water until it runs out from your engine block, replace the hose, start your car turn you heater on and set to hi keep the radiator cap loose until the temp start to rise then close tight.  Once the air pocket had been remover you can drain some of the water from the radiator using the lower drain plug and add antifreeze.

most likely a air bubble in your system. get it up to temp open up your reservoir use something that will fit in the opening and put coolant into it rev engine up a bit until you see bubbles coming up. when you did the engine did you replace cooling system parts like t-stat or water pump? purging the system of air will take a little while good luck hope that helps

To begin with, if you are revving a cold engine to 6000 RPM, you are asking for a blown engine. Most OBD vehicles are equipped with a rev limiter that will cut off fuel at 3000 to 4000 rpm to prevent you from over-revving your engine and blowing it up. If yours is revving to 6000 RPM cold, then the rev limiter, for some reason is not working while it is cold. I have no explaination for this. The best thing I can tell you is to stop revving your engine so high when it is cold unless you really want to see what an engine looks like after is has gone off like a grenade.

1985 Ford Ranger 2.3 starts and idles good. But when put in gear dies until it reaches full temp.


Hmm...........
1985..........
Probably carb? Automatic choke not working? Remove air filter and spray carb with cleaner, Make sure all parts move freely. With engine cold, check automatic choke position. Start and check function as it warms up.

2003 Kia Sedona rpm running high on a cold start.


If it is around 1200rpm for a few minutes this will be normal as the ECM has set the RPM to compensate for the cold air intake (much like an automatic choke). After a few minutes it should drop back to around 1000rpm and then when the motor has been running a bit drop back to around 850-900rpm. If it not following the pattern then run the fault codes and fix the sensor that is reading incorrectly.

Choke problems


I take it that you have a carby in which case adjust the choke cover so that the cam engages the throttle lever and holds the throttle open until the bi-spring in the choke cover moves enough to move the cam out of the away allowing normal idle. If you have efi (Not from your choke word) then run fault codes and see which sensor is faulty. There should be an idle speed around 1200 RPM idle in efi for around 3 minutes and then the idle should drop back.

When the weather is cold, while driving normally, the RPM will just automatically goes up but when the weather is warm, the car has no problem. is there a thermostat or temperature gauge in the car?


Sounds like a faulty temp sensor,giving a false signal to the cold start fuel injector. Normally at start up this will be obvious in a higher tickover rpm than when in warm weather. If it is doing it when driving along then you temp sensor could well be faulty, or possibly the injector itself,a bit like a carburettor choke on an old car.

1995 Mitsubishi L300 Van 2ltr aspirated motor, Automatic choke revs extremely high on cold start, will not decelerate till engine is hot. How can I remedy this?


If it's carburetor & has automatic choke, then there is probably a screw at side of carb, by step cam that moves with choke . Back it of a little at a time until you get desired cold idle speed. Make sure you turn step cam to setting it would normally be when cold, and choke on, then turn screw out to lower rpm's. Look for a little rod from choke shaft, down to base or side of carb area, to step cam.

When I start the engine from cold it runs on high revs too long


Hi ..... This sounds as if it's fitted with an automatic choke, as long as the revs drop when it's warm there is nothing to worry about. The indication when these start to go wrong is that the car won't start when cold ................ even then any decent mechanic can fit a normal/manual choke.
