Simplest would be an inlet manifold air leak. Check hose connections and the slacken and retighten the nuts.

I sprayed around the inlet with some carb cleaner but it didn't seem to do anything

If there's an air leak engine side of the throttle it'll allow proportionally more air in when less air goes through the closing throttle and the manifold vacuum increases.
After market manifold flanges can be a different thickness to the original making it harder to clamp both inlet & exhaust together.
Since it's injection, an air leak on the exhaust side could do similar by affecting the lambda sensor, but you'd probably hear that.
