hi there, trying to help out a friend so bare with me when it comes to exact details

I searched and found similar issues but nothing like what this car has. It will have a rough idle and hesitation when accelerating. came over and read a po303 code.cleared it. checked underhood,couldnt see any cracks on the coil pack and no obvious other signs. started it up,had a slight rough idle(nothing too bad) revved it up and it went away. ran it around the block a few times and no matter what couldnt get it to have any roughness again. came back and cleaned the maf with electical connection cleaner and still no problem. talked to the owner and she said it will go away for a while and then come back with no regularity in intervals.

so if it comes back what are your guy's ideas? spark plug? spark plug wire? coil pack? Thaks for the help
