Re: idle - surging - already checked the archives
Have you done any work on the cooling system lately?? I had the same problem on my 92 EFI Sami one time after I had changed the anti freeze. Apperently the Sami can get an air bubble in the system. When it goes past the temp sender it shuts the engine down temporarily, when the water hits it again the engine starts to run again and causes the engine to surge. It drove me crazy till I found the problem.
Maybe you are having the same problem.
