My thinking is that the MAF was dirty and when you cleaned it you threw it back in and test drove. At that point your engine is running off of LTFT. To get and instant result, ECM must be reset. I have no idea about the possible fueling problems that may have occurred so I may be completely off. Just a thought

 

It ran fine after I refueled it. I was never able to pull a code until after I refueled it either. Then I cleaned the maf and checked the other possibles, been running fine since.

I still think this has to do with intake solenoid, cuz the maf didn't appear fouled at all, but I cleaned it anyway since it was out.
