I have a 2012 dodge caravan. I keep getting a check engine light even after I have changed the ignition coil that was misfiring and all my spark plugs. What should I do the same coil is misfiring?

Check why the misfire first! Checked your distributor points?? Get the engine running OK first, then if the CE light still comes on it will probably be the sensor.

Could be the "New" part you got, I've had to put as many as six [6] "New " parts into a project as those parts were "made in China" and by those that don't care about quality in materials or assembly...
