Hey guys , I need some help..

My 900 Started idling high and will not return to idle. If I hit the throttle pedal it will REV to 3300 -4000 RPM and will not return to idle. If I tap the throttle pedal quickly it returns to proper idle. I have removed the air filter and confirmed the butterflies are closing when pedal is at returned position. NO sticking issues with the butterflies. I have confirmed some free play in the throttle cable as well. I need some suggestions on where to go Next. NO fault codes . Also engine does not start quickly. It seems to whirl and pop. Then the next attempt it starts no issues. HELP
