I have a 2001 exmark with a 26hp efi 1500 hrs. The problem is a mis at high and low idle. The problem comes and goes no rhyme or reason, sometimes it might show up for a minute, sometimes an hour or two, sometimes all day. I have had a new muffler, new oxygen sensor, new fuel pump, and new oil sending unit, new plugs. I put a loaner computer on but the problem is still there. I have had my dealer look at it but they don't have any idea what it could be. I feel like I'm throwing money at a problem That can't be fixed. I'm open for suggestions. It seems to mis under a load and continues for a while. To stop the mis i usually have to code the computer start it back up and in a min. or so most of the time it will clear up.
