Spoke too soon - another problem V70-XC70

I guess I spoke too soon. The car ran great yesterday after sealing the vacuum leaks. After it warmed up this morning, it idled great but wouldn't accelerate, just bogs down. Fuel pressure stays at a steady 42 psi.

Although I replaced the MAF sensor this past winter , I decided to disconnect it and see how the engine runs. Turns out it accelerates fine with the MAF disconnected and idles well too. Hook the MAF back up and it won't accelerate but idles fine. Does this mean the MAF is bad, or is disconnecting it taking another cause out of the picture?

The car has not set any codes, since I sealed all the vacuum leaks found yesterday.

Thanks,
Kcarl
