Persistent misfire codes
Following an engine swap and correcting multiple codes/ issues my 2007 Range Rover HSE continues to throw misfire codes. 90% of the time it's 305 and 302 referring to 5 and 2 cylinders. Occasionally it'll include an additional cylinder today referencing 308. Engine/vehicle runs strong unless I push it. Then it might go limp mode or might not. Seems random.
I have:
-replaced plugs
-switched but not replaced injectors. 302 and 305 remained. Tested fine.
-replaced injector o-rings
-switched #2 and #5 coilpacks to 3 and 4. P0305 and p0302 remained.
-intake gaskets
-replaced purge valve (because I broke it)
Im out of ideas and have only 6 months experience as a Rover owner but learning fast.
Could really use some input. Thank you.
