First you should clean out the throttle body then reset the code and see if it comes back,

did the Missfire code go away?

I tried cleaning out the throttle body & got a lit of black slime out of there, however it did not cure the problem. Maybe the injector circuit? PS Thanks so much for responding to the querry so promptly.

Next change your PCV valve and make sure the hose and the rubber boots/elbows are not rotted or cut
