Re: misfire
Did you clear the code(s) when you replaced those items you listed above?
You could have clogged injectors or a wire shorted out.

Re: misfire
check the cam sensor and make sure the gound wire for the module is good the braided one under the cover over the plugs.

Re: misfire
If the cam sensor was the problem, he would most likly get a DTC for that, not a msfire.
 Check the Ohm resistance on the injectors, paying attention to their difference's.
