my 1993 start up find but in gear it shut down ,when the car get warm.
the only thing I did is put in spark plug and change the air filter then everthing went bad

 

Hi 7046fred: your description is too vague to tell the problem. Please read the sticky "the unofficial user's guide to the mazda protege." It does not matter which year protege. Check the things that are listed, vacuum leaks, MAF sensor etc. Let's see if you can find some things that are out of order.
Report the things you do and how the car responds.

 

I change mass air flow senor same thing happen. NO Vaccum leak


it run while cold not


help

 

7046fred:
I really like to help you. But we need to be able to communicate. It does not matter if your English is not perfect, as long as I can figure out what you want to say.

From your first post I can tell that your engine runs when it is cold. It stops when it has warmed up.
Your second post tells me that you changed the MAF sensor. But I don't understand this sentence: "it run while cold not "

I like to know: how many miles or kilometers are on the car.
did you clean the throttle body?
Is the Check Engine Light on or blinking?

 

do the engine run ok when cold? no misfires? for what i can tell, the car run ok while in open loop. but dies when it warms up. thats when the car goes into closed loop and some sensors are used to control the engine.

 

Put your old spark plugs back, put your old air filter back in. Make sure everything is plugged in & connected. Double check there are no cracks in the large rubber hose going from your air filter box to the engine.

 

ok the car run in gear cold. It has 1 92000 mile, no check engine light is on ,
no I did not clean the throttle body but its looks clean


I throw away the old spark and filer I also change the intake hose

 

As grim reaper said: make sure everything is plugged in. Look for every wire harness. Unplug, clean and reconnect it. Look for the connectors to the MAF sensor, HO2 Sensors, Air Temperature Sensor and ECT (Engine Coolant Temperature) Sensor.

Did you get a new MAF sensor? Did you throw the original MAF sensor away?

 

check the egr valve too.

 

I cleaned and checked every wire on the car and the same thing happen.
