Hey new to the page, I have 08 750 with fuel optimizer and a HMF exhaust. So it runs fine but when I let off throttle to slow down it dies. When I try cranking back up it flashes the FI light. And after a few seconds it will dies back up and run fine. Any ideas on why it would die when I let off throttle? Thanks

Does it just do this once when it is cold? Or does it do this every time you let off the throttle, even after it is warmed up?

Does it every time I had a muzzy exhaust and it has a fuel optimizer on it. With the muzzy I didn’t have this issue. The packing came out of muzzy is why I have a hmf now

Having the same issue when cold. Recently picked up an '08 with a Penland HMF exhaust.
