Sounds like you need to remove your
MAF/
IAT sensor from your air intake and give it a clean out "Be damn carefull with it! it's not cheap!!" use a non oil/residue leaving electrical contact cleaner.
I'd consider googling it, probably not the first case of this happening.
Maybe remove inter cooler, and dry out.
Could even consider dropping the oil/changing? Should need to go that far?! Never know..
Maybe give a few workshops a call in the morning and ask them what they think.
