Was cruising on the highway yesterday and all of a sudden i was running rough and noticed my A/F was at max.

Checked the DTC and had P0203,P0302 and P300 and I am sure I saw misfires on cylinder 5 and 6.

Drove around my house then to see if it was random, but was still getting misfires.

Then when I tried again after an hour, just for like a few miles, There were no misfires.

Today I swapped all injectors, coils and spark plugs and been driving for about 50 miles and no misfires yet.

I want to keep a close eye on things , any suggestions?

I have a 2015 V6 stock with 118K miles and the spark plugs had 20K miles. Had it installed at a shop.
