i had the exact codes and problem you bearly hear a mis at idle and it goes away as you rev.
mine was on cylinder 2 the injector oring went bad.. the injector actually wabbled around in the hole so i replaced the oring and put a litle white grease on all of them before i reinstalled the injectors. took about 45mins to fix. not a beig deal. all the codes went away after i fixed that. i didnt think to look there cause there was no oil or gas leaking but i think it just disapated after leaving the cylinder or something. try it i bet it works.

Awesome bro. Cause I was spraying brake cleaner to see if it would leak into anything indicating a leak and it acted like it got into injector 2...could you visually see something wrong with the oring and where did you get a new one at?
