I start the engine, and can not continue runing in low speed, then the engine stop runing

You have rvc/regulated voltage control, that circuitry is in your pcm. I'm not saying the pcm is faulty, at the moment, I don't know? You also have a battery temp sensor in the battery tray housing, that might cause problems?
Check for applicable charging system trouble codes, if you haven't already.

With a volt meter test the wire voltage at injection pump connected is should be at less 10.8 volts cranking and test continuity of fuel shut off solenoid about 50 ohms. (guessing) higher number would mean that is can not create enough magnetic power to pull the solenoid on. but low voltage creates the same affect. voltage drop from key to pump is your problem.

spark plugs injector cleaner have u been runing with low fuel pump may be on it way try fuel injector cleaner & fill tank 90 plus octane

Most low idle speed problems on these engines are due to a faulty idle air control valve but since you state the idle will go up and return to idle then i would say it is working properly i think you have a throttle body coking problem ( dirt and grit accumulates around the butterfly valve in the throttlebody ) to fix this simply remove the fresh air hose from the throttlebody and open the throttle all the way up use a clen rag and wipe clean you may use a solvent such as B12 on the rag but dont use too much

you need to have the slow runing jet in your carb adjusting

In all probability the thermostat stopped working, and it is not blocking the flow of fresh water from radiator. The only way i can think a sensor might lower engine temp, is by tripping the fans continuously, and even then a thermostat in good working order would block water flow, and let engine reach normal operating temperature. With the engine idling, in park, with the a/c off, if the temp is low, look in the engine bay, and make sure that the fans are NOT working.

You should have a code stored if this is a engine misfire. But most likley, providing nothing major is present, then I would suspect you need spark plugs and a coil may of failed because of it.

check the tick over speed if its slow, less than 850 950 rpm in gear that why it shimmeys,, the engine is trying to stall in gear,,,if you need to bring up the tick over speed have some body in the car holding the brakes down for you as it needs to be ajusted with the car in gear,,and running yourself over hurts??? the car should just creep forwards with the engine runing in gear with the brake off,,,tickover speed of 950rpm

check the map sensor,,unplug it while running to see if it slow down or shut off

you mean you turn the key of and engine keeps runing? if that's right posible some one conect you radiator fan to a ignition power and that keeps engine runing because the fan keeps turning and acts like generator putting power back to system, but if not let me know and don't mark my answer as inapropiate,
just can figure your question, you know what's bad? with this web page, than i'm here i will say may be waisting my time trying to help people for free and then after that people still mark my answers as inaproiate, is that fair? whell good luck and let me know, good luck
