popping noise on 1996 Mercury Tracer

I have a popping noise on the drivers side of car, check engine does come on. When i start the vehicle sometimes it idels good and some times it dies after a few sec but then it will start up, when i start driving the popping noise starts right away and sometimes it takes awhile but when it pops the car chugs like its either not get gas or something with air flow. The tps and mass airflow have been changed kind sounds like it's up by the fire wall. Sometimes when it happens the car won't start till after a few mins
