Hi all,
So I’ve been having this p0306 code for several months and it’s driving me crazy because I can’t find the solution to it, I’ve tried basically everything I can think of to fix this misfire code. I’ve changed the rail, I’ve changed the spark plugs and changed the #6 plug again to make sure that one wasn’t bad, swapped #5 and #6 injectors to see if the problem followed and it didn’t, sprayed around with brake cleaner trying to find a vacuum leak, did a compression test, did a fuel pressure test, all looked good. I just checked my 2 smaller cats and there’s about a 60 degree difference between inlet and outlet of one and about an 80 degree difference in the other. Every time I scan the code is says it’s right around 700 rpm that the misfire happens. Also I can feel it when I’m idling - it’s kind of like it has a small cam but when I’m at higher rpm for a while it’s fine. Any ideas would be appreciated.
