So this past summer I had a world of trouble with my bike. First of the year last summer I started it and it was giving my a fault code of 15, took it to the dealer and they cleared the code and replaced the plugs. Two weeks later same thing happens. They change a TPS and it worked for another month and a half. After that the bike died on me going down the highway, it would idle but no throttle response. Took it back to the dealer and they think it could be an ECU issue. My new problem now is the bike will start up and run like a top first thing but after I go a few minutes down the road, shut it off and start it up again it wont idle unless I keep the RPMs up, then I run it for a bit down the road and it works fine. Any input would be a great help because as it sits now I'm looking at spending $1200 on a new ECU that I'm not even sure is the problem. Thanks!
