I have a brand new (7 hours) mini with the honda motor. After the engine warms up the engine light comes on at idle. My dealer claims that they have checked with the hustler and the honda people both of whom can't offer an explanantion. I read a thread several weeks ago from someone who had the same problem and they said that their dealer told them that honda left a part out of the engine. When I explained this to my dealer he thought I was nuts. I need help.
