Yamaha F115 2003
Hello,
I have a new problem on my F115: my idle problem still remains because ECU starts in error at 900RPM (perhaps ISC but I have no laptop) but motor ran great at all RPM.
Now, after running around 10 minutes at 4000 RPM, it begins to stall: if I throttle problem disappear and it runs fine up 5600 RPM and if I come back to 4000 RPM problem remains 10 minutes after.
Do you think this problem is due to my idle problem, ISC for example, or another one ?
Many thanks
Lo?c
