Narrative:

At 7000 ft I was advised by approach to expect a visual approach into aik. After getting ATIS; aik was reporting 1700 ft. I advised ags I would do the GPS 7 approach. I was cleared to descend to and maintain 4000 ft; while waiting on a king air to complete their approach. I was vectored with several turns. After the king air reported canceling IFR; ags controller cleared me to 3000 ft and maintain this to the IAF (vixly) and established on the final approach course. Though he said pepci; vixly and pepci are close inbound. When I put the approach into my GPS (garmin 530) I mistakenly accepted the FAF (pepci). I descended to 3000 ft and headed for pepci (I should have been going to vixly). The controller questioned what I was doing. I decided to go missed approach since I was not following his clearance and adding power and thinking I should return to 4000 ft I climbed to 3300 ft or 3400 ft then realized I should be at 3000 ft. Went to vixly -- did the procedure turn and completed the approach to runway 7 correctly.
