The code is for a cylinder one misfire, so we know whee to start looking, first thing to do is check for a vacuum leak around that cylinder and do a compression test as well. If you spray a little brake clean around the inlet gasket while running if there is a leak the revs will alter, or you can listen for a whistle with a length of small hose. Both methods work well, re-post for further assistance if required.
