Private pilot of small aircraft aircraft deviated from clearance altitude and track due to distraction from a rough running engine resulting in ATC assistance in getting back to original clearance track. This pilot also lined up with the wrong runway when cleared to land upon returning to the departure airport.

Narrative:
While on an IFR flight plan to phoenix immediately after completing IFR departure procedure out of poc, I noticed engine roughness and focused on proper procedures to reverse the problem. Unfortunately I was unsuccessful, and while my attention was diverted, I strayed from my required airways and missed an altitude clearance from ATC. I then attempted to navigation back on route and received vectors to my airway from ATC. However, I decided to return to poc because of my situation. Brackett (poc) was reporting IFR, and I shot the VOR a approach into brackett. The approach went well except during the circling maneuver, I requested 26R during final, instead of 26L, as I was cleared. I was positioned more appropriately to land on this runway. I received clearance from the tower for my request to land on 26R and landed. I feel that I fell victim to cockpit overload. While my attention was diverted, I failed to adhere to my IFR route of flight and did not comply with altitude clrncs. It had also been some time since I flew IFR airways. For now on, I will try to detect all engine malfunctions on the ground, and fly IFR with an instructor until more confident.
Original NASA ASRS Text
Title: PVT PLT OF SMA ACFT DEVIATED FROM CLRNC ALT AND TRACK DUE TO DISTR FROM A ROUGH RUNNING ENG RESULTING IN ATC ASSISTANCE IN GETTING BACK TO ORIGINAL CLRNC TRACK. THIS PLT ALSO LINED UP WITH THE WRONG RWY WHEN CLRED TO LAND UPON RETURNING TO THE DEP ARPT.
Narrative: WHILE ON AN IFR FLT PLAN TO PHOENIX IMMEDIATELY AFTER COMPLETING IFR DEP PROC OUT OF POC, I NOTICED ENG ROUGHNESS AND FOCUSED ON PROPER PROCS TO REVERSE THE PROBLEM. UNFORTUNATELY I WAS UNSUCCESSFUL, AND WHILE MY ATTN WAS DIVERTED, I STRAYED FROM MY REQUIRED AIRWAYS AND MISSED AN ALT CLRNC FROM ATC. I THEN ATTEMPTED TO NAV BACK ON RTE AND RECEIVED VECTORS TO MY AIRWAY FROM ATC. HOWEVER, I DECIDED TO RETURN TO POC BECAUSE OF MY SITUATION. BRACKETT (POC) WAS RPTING IFR, AND I SHOT THE VOR A APCH INTO BRACKETT. THE APCH WENT WELL EXCEPT DURING THE CIRCLING MANEUVER, I REQUESTED 26R DURING FINAL, INSTEAD OF 26L, AS I WAS CLRED. I WAS POSITIONED MORE APPROPRIATELY TO LAND ON THIS RWY. I RECEIVED CLRNC FROM THE TWR FOR MY REQUEST TO LAND ON 26R AND LANDED. I FEEL THAT I FELL VICTIM TO COCKPIT OVERLOAD. WHILE MY ATTN WAS DIVERTED, I FAILED TO ADHERE TO MY IFR RTE OF FLT AND DID NOT COMPLY WITH ALT CLRNCS. IT HAD ALSO BEEN SOME TIME SINCE I FLEW IFR AIRWAYS. FOR NOW ON, I WILL TRY TO DETECT ALL ENG MALFUNCTIONS ON THE GND, AND FLY IFR WITH AN INSTRUCTOR UNTIL MORE CONFIDENT.
