02 mitsi lancer. I start the engine in the morning it chokes a little then dies. When I turn the key again it starts straight away. It starts up fine when the engine is warm too. mini service done.

Before you start it cold, prime the fuel pump twice or three times. Lets make sure you have adequate pressure.

Check the choke and make sure that the choke is all the way open when hot. The choke should only be closed when cold. The choke can be adjusted on the side by loosening the 3 screws and wathcing the butterfly valve.

Have to stick screw driver down carb to open flappers to get started then the 1988 350 rins bad and if stalls it wont satrt again.

Your carburetor has an electrically controled choke thermostat. In addition to this you have what is known as a choke pull-off diaphram. this pull off over a peroiod of time wears through the rubber diaphram and it fails to open the choke the necessary amount to stop from choking the engine out completely. Now, during this failure your sparkplugs have become irreperably blackened with fuel soot and they cannot be cleaned. this is why once your engine warms up it will not run because fouled plugs will only fail when they are warm. You need to have your choke thermostat, your choke pull-off valve and your spark plugs checked and or changed.

Check the choke when cold. When its hot take notice that its opened. Upon starting next time when its cold look at the choke and see if its closed fully. It should be. If not push the throttle all the way open and let it retract closed. The choke should close when the engine is cold. If it does not the vacuum break is shot which should be the rear one that controls the choke. Yours may be on the front since some are but very few are made on the front

To start up a cold engine requires reach mixture (air-gas).In your case it seems like the choke is not working ,so cold engine cannot start.If it is an injection operated system then it must have a temperature sensor which suppose to turn the choking on when cold engine needs to get started.Either the sensor is faulty or the choke or between the two there is a faulty connection somewhere.

Does it have a carburetor or is it fuel injected? In 1986 it could be either way. It sounds like a carburetor with a choke problem.

Stalls when engne warms up

Your ECT (Engine Coolant Temp) sensor is bad. What's happening is at cold start it richens up the fuel mixture and as it warms up the ECM thinks it's still cold and essentially the "choke" is still on. Also check your coolant level. If you don't have enough coolant in you engine/radiator, the ECT doesn't know what to do so it thinks it's cold.

Yes you do need it. It's purpose is to allow less air during cold starts, and then it gradually opens as the sngine starts to warm up. They make automatic chokes, and manual ones you open and close with a cable.
