Mitsubishi HJ Series Galant Hatchback year 1994. Faulty Motor doe
Motor was performing OK.
When tried to accelerate on small hill, engine did reluctantly but came good again when road leveled out. Then I had to stop at next traffic light, engine stopped and started again and run to next traffic light and stopped running but started once again in order to cross intersection and then stopped completely and could not be started anymore. No shortage of fuel as it pumped always when engine was started. Ignition was checked and spark on plug is available. Suspect faulty Injector System ?? or irregular Air Lock ??

Usually a sign of a fuel problem, either too much or too little.
Too much could be several problems including a clogged air filter, too little could be a weak fuel pump or other issue.
A mechanic would check fuel pressure and air flow first.
With the filter this motor is right @ 4.5 quart. In practice most will put in the full 5 quarts with no issues. The extra .5 quart will not cause the crank to splash in the oil.
I hope the may have assisted,
this maybe caused by no fuel or faulty fuel pump, ignition coil, wire and plug crank position sensor. first check for spark by removing on spark plug wire and put a spark plug in the spark plug wire boot, donot touch the plug only the boot have someone crank the car over. if you see spark, that part of the ignition is good. if not, check the coil resistance if should 40 to 80 ohm with a volt meter pf not replace. if ok, but no spark check the igniton control madule make sure the coil and module are receiving current. if not check the fuse that feels them. if it is ok, check distributor cap and rotor. if rotor and cap are fine, check for fuel at either the fuel filter, the fuel return line or removing some spark plug and see if they are wet. if there is no fuel check the fuel pump and the fuse and relay that control the pump. if there is fuel with high pressure but there is no spark, check the crank sensor for signal with a volt meter while cranking the vehicle
it could be the spark plugs, at least that is what it was for mine, if you have over 50k miles without a spark plug change i highly suggest one, also a oil /transmission change would be great for your car too if you haven't done those reciently. I would also suggest using a higher grade gas, sometimes this fixes the trick too.
If you try all those and still experiencing hard transitions please let me know and i'll try a more indepth analysis on your car.
