So i swapped a z6 intake manifold onto my Y7 and started up and it went straight to 2000rpm and i watched it warm up and stay at 2k rpm and not even budge from there. But after shutting it off and starting it back up it was idling at 1200(i know the idle is because of the cable or throttle rocker i checked that out first). So i am not sure what it could be. Maybe coolant hoses not proper on the iacv. There are no vac leaks i went to the two spots i had to block off and checked using a spray of soapy water to check for bubbles or water getting sucked in a bit and nothing. Anyhelp and advicr in the matter is appreciated.

Thanks, Leviatard
