I have a 2007 Kia Rio 4 cyl that keeps setting a p0300 p0301

Customer Question

I have a 2007 Kia Rio 4 cyl that keeps setting a p0300 p0301 and p0302 after engine warms up it seems to run fine there is no noticible misfire observed while running maybe a slight engine roughness at idle. I have replaced plugs, I have swapped coil packs to different cylinders and also removed injectors cleaned and switched positions on them as well. After doing these things it made no difference it still sets the same misfire codes. Random and cyl 1 and 2.. I am needing direction where to go to next to eliminate the random misfire codes..
