ran out of gas light never came on got fuel started check engine light came on

What is your question?

While driving the it felt like it wasnt getting any gas and would shake and felt boggled down till I hit second gear. Had engine light code read and said it was spark plugs. Replaced them and engine light went off. Later driving it came back on an car was doing the same thing again. Had engine codes read again and they code couldnt pin point the problem. Read on other sites possible coil pack, fuel injector, etc. Does anyone have any clue as to what the problem is? Also it has 155k miles. Ive replaced the battery 4 times, altinator 4 times, pcv valve, and intake manifold all within the last 2 years. Please HELP!
