My niece bought a 2014 spark over a year ago, she's brought it to me for several minor problems that I took care of. Now it had a p0301 code and p219a code. I changed spark plugs, cleaned mass air flow sensor,(which looked pristine) and made sure I installed the coil packs in different cylinders. Now it is throwing a p0300 code which leads me to believe it is a coil pack, I'm waiting to see if it narrows the code down to one cylinder. Has anyone else had this problem? And what corrected it

Hey, did they tell you what the problem was at the service center?
