Ski doo etec 800 idles fine but will sputter and run terrible when opened up

[Tylerjm18]

I have a 2011 ski doo summit 800, i was told it just needed plugs. Changed plugs it ran better than when i bought it but now it wont open up and seems to be running on one cylinder, it has spark on both side and idles fine. Im thinking its dess related, thanks

Does it rev up enough to engage the clutch?

Yes it will rev up to about 6500-7000
