why is my number 1 cylinder misfiring?

What is your question?

I have changed the coil pack twice and the spark plugs. For some reason the engine light comes back on and the car starts misfiring again.

What makes this problem better or worse?

nothing i put two coil packs on work for a few days goes back to same problem

How long has your 2011 Chevrolet Aveo had this problem?

about a year dont drive car now because of problem
