Hello there i was up at trimont minnesota today and watched there mud run and rode there trails at elm creek, lots of fun after the rain. Before i left i got a check engine light and a code 51, what do i need to look for to solve this problem? When the check engine light comes on the it spit and sputter at low rpm and go away at 4500 rpm and above, i have good fuel pressure and a new fuel filter. Any help would be greatful!!!!

 

i think u can find out what the codes mean in the manual. if it dosent say what they mean just call polaris and ask them.

 

I have an 06 800 and the code 51 has to do with injector 1 . Its either Open load , short circuit to ground or short circuit to battery.

Check your coil gound...

I cleaned up all of the grounds on the atv and added a extra ground from the coil to the frame and i still get a slight miss and a code 51, any other suggestions or ideas?

 

I just ordered a new coil and plug wires to see if this cures my problem. Any other suggestions to check or look at? I cleaned all of my grounds and fuses and added a ground strap to the coil and when it gets warmed up it starts to miss and i get a code 51 still, it only happens for a few seconds and goes away for a while and starts over.
