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?

No check engine light has 38 psi of fuel pressure. Spark plugs are auto light and gaped to spec

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
