Narrative:
Climbing through FL180, left engine began to run rough. We declared an emergency and decided to divert to gallup, NM. Callback conversation with reporter revealed the following information: the reporter stated the engine roughness was intermittent and was very noticeable and with no delay the decision was made to divert. The reporter said the work performed at the diverting station was replacement of the fuel control module. The reporter stated the next day another crew flew the aircraft and returned with the same report and the aircraft was grounded. The reporter said maintenance found a chaffed wire that when grounded, pwred the propeller feathering circuit.
