2015 CX-5 2.5L
Over the past 6 months the CEL has come on multiple times and the code is always P0301 - Cylinder No. 1 misfire. No detected driveability issues
After the first time, I just went ahead and replaced the no. 1 ignition coil ( the plugs were all replaced just over 20,000 miles prior - NGK Iridium long life). Cleared the code and for the next month or so, all was good.
CEL came on again, so I replaced the plug for the no. 1 cylinder and swapped the no. 1 and no. 4 coils. Cleared the code and all was good for about another month.
CEL came on again, so I installed another new coil for the no. 1 cylinder. Cleared the code again and all was for good for another few weeks.
CEL came on again. Did nothing this time and after two weeks the code cleared by itself.
CEL came on again for a few days and then cleared.
CEL came on again for another few days and then cleared again.
I am at my wits end as to what is going on. Any ideas?
