Do you have a check engine light?

Check the fuel pressure if its within specs and engine compression. Sparkplugs is it OEM part and gapped according to specs?

I don't think the pick-up coil is the problem here

A misfiring problem can be caused by compression, fuel and spark issues-its not easy to fix it requires extensive diagnosis
