Here are some commons causes, hope this helps.

Air leak in the intake manifold, or in the EGR or EVAP system
Base engine mechanical fault that affects one or more cylinders
Erratic or interrupted CKP or CMP sensor signals
Fuel delivery component fault that affects one or more cylinders (contaminated, dirty or sticking fuel injector)
Ignition system problem (coil or plug) in one or more cylinders
Vehicle driven with low fuel pressure or while very low on fuel

The passenger side front cylinder is #1.

Multiple cylinder misfire


There could be a couple of reasons for this. If you are getting multiple misfires then usually it has something to due with the plugs going bad. It also depends on how many miles you have on the plugs and the wires. The other problem could be with the ignition coils or the ignition module.
