Hi guys, the other day I was driving home from work (2002 Rodeo 3.2L v6)and felt a vibration from the engine and it wanting to die at red lights. I scan the computer and got a p0304 code. I changed out the spark plugs, they were due anyway. Nothing abnormal on them other than old and worn. no help. So I swapped #2 + #4 coil pack and erased the code. This time I got a p0300 muti misfire code. When I swapped them back I got p0304. Do I have a dual failure going on here or am I missing something when I swapped the packs? Until the other day the truck ran smoothly.
