I think you need new spark plug cables. Try this at night. You'll need a partner. Have them, with emergency brake on and both feet firmly on brake pedal, start car, put in drive, and give a little gas. Now while they are doing this, you should pull spark plug cords one at a time off of plugs. You should be able to see sparks jumping from the cable when held close enough to plug or engine block. I would almost bet that you won't see any spark from at least one of the six. Maybe two. You will need to cover up or pull out the little light bulb under the hood to make it dark enough to see sparks. No spark=need new cable(s).

The causes for cylinder 2 to misfire in a 2001 Chrysler Sebring with a 3.0 engine is a faulty spark plug or a damaged spark plug wire. In-depth troubleshooting can be completed by a local mechanic or dealership.
The crankshaft and camshaft sensors monitor engine speed. When the sensors detect a change in speed, they attribute it to a misfire. Depending on the cylinder that was supposed to fire, the engine can determine when the change in speed took place and can single out a particular cylinder. When it happens with more than one cylinder, it becomes a mulit cyl misfire. This is one of the symptoms of a malfunctioning cam or crank sensor.
