08 Sportsman 500 EFI sputters when wet
Hey all great forum I must say:-). Having aproblem with my bike. The other weekend I was out riding, lots of deep water and mud, bike ran fine. The engine HOT light came on, so checked the rad and it was pretty dirty, shut bike off and let it cool down. Started bike up and next puddle i'd say about 6-8" deep I hit fairly fast to try and clean out the rad a bit. After hitting this puddle and water flying everywhere the bike would cough and sputter when I gave it gas, basically ran like crap. First time it's ever done this and I've hit some puddles pretty fast before. Let the bike sit over night and ran it the next day everything was fine, so I assumed that I had hit this puddle to fast and something got wet that shouldn't have. Today I washed the bike off with the power washer like I've always done without any problems, and now it's doing the same thing. Any suggestions as to where i should look first? Thinking maybe spark plug boot is getting wet? Anyone else had this problem?
Any help is greatly appreciated.

Ok it's been awhile since I posted this. I put dielectric grease on all my wiring connections including the spark plug boot. This past weekend, hit a bit of water again and same thing happened. Bike runs like crap, idle is all over the place, backfires under load and dies, seems to miss going down the trail if I can get it going that is, stalls out when throttle is applied sometimes....oh and reverse speed limiter seems to be way lower.....won't let bike go over 2200 rpm in reverse before limiter kicks in now, not sure if it's related or not.

K think I've narrowed it down to the throttle position sensor, whenever i pour water on that bike starts running like crap. However when I get the blink codes codes 41 and 44 come up, ones a crank position sensor and the other is ait temp sensor i think....so not sure why water affects the TPS sensor.....
