Please help Intake runner control solenoid

[Redsped 3]

Recently I’ve been getting a code at idle stating fuel system lean at idle. So I then sprayed all my vac lines with carb cleaner and found that my intake runner solenoid is the source. Just to make sure I smoke tested the solenoid and it was leaking like crazy. I now have 2 more that I bought one being brand new and the other off another Mazdaspeed. After installing the new one my LTFT was at 20.12 same as before so I took it all off again. I then smoke tested both of the the solenoids I got and To my surprise both of them leak out of the top of the solenoid. Has anyone else had this problem and any way to fix it?

Please post a photo of this solenoid in place. "Intake runner solenoid" is not a term often mentioned here and there are quite a few solenoids activating things around or close to the intake manifold. Perhaps we know it by some other name.
