2018 Brute Force Idle Issues

Working on a 2018 Brute Force 750 that idles high enough that it engages the clutch. I cleaned the idle control valve earlier and it seemed to fixed it but it started idling high again. So I tried cleaning it but that did not help this time. I finally replaced it and that also did not help. I've checked linkage it is good. I've tested all sensors according to Kawi service manual and they check out. I replaced plugs and nothing seems to help, it continues to idle way to high. I also counted the turns and cleaned the small air adjustment screws in each side of the throttle body. Battery is good and it is charging. I also replaced intake boots between TB and engine. They were starting to crack but didn't seem yo leak when you sprayed starting fluid on them. Fuel pressure is good. It runs great but will not idle correctly.

So I thought I would mess with it some more before I posted this. The neutral switch was not working so I grounded it out and anytime I have it grounded out it will idle down. As soon as I disconnect neutral switch and give it throttle it won't idle down until I ground out the neutral wire.
