I replaced the lower intake that was leaking antifreeze and put everything back just as it came came off and I replaced the plugs when I i fired it back up it sounded good but when drove it I kept dieing but ran good when it ran so I cleanded the coil pack up good it stoped dieing but fell on its face when I dove it I changed out the coil pack stiil ran the same. Ran fuel pressure check it was good. It set a code of multiple miss fires I checked every looked good but still fell on its face. Then it also ran a map sensor code so I am extremely lost! Any help would be great.
