Sr20det idle surge

My idle is fluctuating rapidly from about 1800 up to 2400 rpm

Sprayed carb cleaner at every vacuum connection
Switched iac's
Switched maf's

No idea what could be the cause for this! Need some input. I have the greddy intake manifold if that's of any help
EDIT: problem was a leaking IACV gasket
