My 99 750 Gixxer FI light came on, I checked for the code and it was C14. I replaced the sensor then the FI light came on again, C13 came up, I changed an other sensor.
I went for a ride the bike started cutting out sparaticly,then ran normal but the FI light stayed blinking, I checked the code and C13 & C14 came up. what the hell is going on. please advise.:banghead

i think that's the IAP sensor (C13) and the TPS sensor. (C14)

when you see the code, where is that dash? _C13 or -C13

you may try to flash the ecu: unplug battery, unplug ECU...wait....wait....plug in ECU, plug in battery. And see if that erases the code from the memory. But if you still have a problem, the code will show up.

I don't remember where the dash is, the code erases when the bike is shut down and restarted.
I'm still going to unplug the ECU and battery to see what happens.
the battery is new.

Dude, I can't believe that unpluging the battery would fix the bike and stop it from running like shit. I rode it for 100 miles today and no more problems.
THANKS! from SOCAL.

:cheers glad it worked out
