Narrative:
It was solid IMC at 8;000 ft. I began have engine problems. Rough running; sputtering and then coming back to life; and surging. During the time of troubleshooting the engine problems I drifted up to 8;300 ft. ATC pointed out my altitude and I descended still trying to get the engine running smoothly. Shortly after I was given a clearance to 11;000 and to 18;000 ft. I climbed up to about 14;000 before deciding to abort the flight. I then received clearance to return to my departure airport. We immediately checked the magnetos for operation and found one to have quit. After I was given clearance to 11;000; ATC gave me a phone # to call. I called as soon as I landed; gave them all my information; and explained what had happened. They said they had to write this up as a possible altitude violation due to loss of separation.
