Narrative:

I was flying a seneca I and was doing a VOR approach. On the climb out after going missed; I felt a loss of power in my right engine. The oil pressure and temp were fine; I had fuel; fuel selectors were on. I put the fuel pumps on and attempted to find the problem. The right engine was still producing power but I noticed the right throttle lever did not indicate a manifold pressure increase when I moved it forward. For precautionary reasons; I shut down the right engine; feathered the prop and secured the engine. I notified the control tower that I was landing. After landing; I taxied off to our (flight school) ramp area and restarted the right engine. It started up immediately but I could not increase the manifold pressure with the throttle lever. It ran at the RPM setting after the engine start. I surmised there may be a problem with the throttle cable. Other than that issue; the aircraft ran fine.
