Looks like F1, but actually means FI, Fuel Injection.
Throttle body. I had to replace mine a couple months ago. FI light came on for a while, ran fine for a couple months with the light on when it was cold, went out when warmed up and restarted.
Then, boom, one day no power. Only could go 30 mph. I got a used part on eBay for $80 as New was $600 and not in stock.
But could be any of a myriad of things. Even just a bad connection. the throttle body and no less than six electrical connections. That's just my one experience though.
