Hi,
I also have number five cylinder misfire. Change the ignition coil and spark plugs.
Here is how I got to this situation. Mine only happens at high RPMs as I was passing Somebody the engine light came on engine ran rough.
Engine light, then went off truck ran fine. I did a test and floored it again. Engine light came on and stayed on, went home and found the code PO 302 number five cylinder misfire. I changed the ignition coil did the test same roughness high rpm but light never stayed on. Cleared the code did it again high rpm light came on ran rough light went off. Change the spark plugs same thing. Getting ready to swap out fuel injectors to see if that’s the problem. Any ideas?
