05 900 plug fouling and dieseling

[stickshift69]

Hi all been a while. Just cleaning up the 900 RMK for the winter and need to address some issues from last winter. Has SLP Pipe and map.

-After warm up every second or third ride the sled will die, I replace the plugs and good to go again.

-When warm shutting down it takes a while for the sled to idle down and will "diesel" (keep running) after I hit the kill switch. This happens quite a bit.

sled runs great otherwise. 87 or 91 fuel makes no difference. Don't run oil in the tank.

Parts changed within 1500 miles:
-Stator
-TPS (set correctly)
-Reeds
-Motion Pro Cable
-Fuel Pump

Parts not done since new:
-Coolant sensor
-Exhaust sensor
-Coil
-Injectors.

Any directions will be great. Long live the 900... Ill be here a while!

Would like to add that Im running an Indy Dan TM3 with about 3000 miles on it and 06 pistons

CEL on or flashing?
Fuel pressure is?
TPS set, harness checked? With throttle bodies in correct position!
ECT Exhaust probe checked?

No engine light or nothing. I have one of the homemade TPS setting tols made so it should be good or damn close. This just started happening one day so almost can rule that part out. I have not tested the exhaust sensor was thinking about just changing it.

It's running rich then. When was the last time you changed the exhaust sensor and the air intake sensor?

Oh I forgot to ask though, did you do the tps wiring harness pigtail update?

What to the plugs look like? make sure you are not loosing antifreeze. I had a head gasket melt a little. as it got to hot and started burning antifreeze . so plugs were fouling out. something to check
