F I light on when running

i have a 00 rc and my fi light is on it blinks 1 time and has a 4 to 5 sec pulse then light up 1 time then a 4 to 5 sec pulse u get the point so i am thinking that 1 blink =map sensor.
does that sound right but the bike seems to run fine but hard to start and then some random stalling but with the bike running i unplug the map sensor and the bike idle like crap and stall ? any help would be good

Well 1-long & 4-short blinks is a code 14, which indicates loose or poor connection on #1 injector on cylinder #2.
And 1-long & 5-short blinks is a 15 code, which is injector #2 on cylinder #2.

Troubleshoot the wiring and electrical connectors of both both injectors.
Then again, it could be an electrical problem with the injector itself.

Well a code 10 is a faulty BARO sensor (on the front of the snorkel), or related connector or wiring.
The engine will run, but will run worse the higher the altitude.

Do you have the service manual in paper or electronic form?
If so, go to the troubleshooting section for code 20.

It could be a problem with the baro sensor connection, the ECU connectors, an insufficiently cleared EEPROM memory, or the ECU itself.
Run through the steps to try and isolate the problem.

You've gone from a code 10 to a code 20, so maybe something's up with the baro sensor connection.
