In order to replace the sparkplugs you must remove the upper manifold runners. remove air cleaner box cover and the remove air cleaner box remove the five bolt holding the runners to the base manifold. Now remove the two support bolts under the throttle body. Now you should be able to lift the runners and support with wire from hood. now you should be able to replace the sparkplugs. I reccommend replaceing the wirs and using dielectric silicone grease on the wires and new plugs. These PTs are noted for plug wire failures

Could be spark plugs, spark plug wires or the cell pack. I've had the same problem with my 2005 PT Cruiser and it was the plugs that needed changing.
Yes.
There is no such part on a Chrysler PT Cruiser.

Tuning up a Chrysler PT Cruiser can be done at home or by a mechanic. A tune up will consist of an oil change, changing the spark plugs and wires, air filter, and distributor cap.
Did you change spark plugs lately? If you did you could get vacuum leak in upper air intake manifold - 4 rectangle shaped gaskets.
