I'm just reaching out too see if there was ever a solution found. I have identical symptoms as I rebuilt the motor in a 18 800 trail and now the fuel will get shut off to cylinder #1 after idling for just a few seconds but if the air temperature and pressure sensor is left unplugged it runs fine other then a rough idle when its cold.

Hi, is about CFmoto Z8 2014,after I rebuilt all the engine,put all together start ok,run ok on idle but the cylinder #1 won't run,I got spark but fuel is shut off about 4 second after I start de engine,I swap O2 sensors,injectors,coils,the same results.

If I unplug the T-map sensor( air temperature and pressure sensor) will run ,not so steady idle but will run strong,EFI light is on.

I have changed ECU too,but no changes.

No errore codes on dashboard.
The service manual is so vogue.

I have the exact same thing going oh here, did you ever find out the problem?
I found out that if you unplug the map sensor, it doesnt drop the cylinder and it runs pretty good, but wont idle well.

Any info would be great! Thanks!
