Need Help S60 Rough idle, need guidance

Here is what I have:

2001 S60 T5.

It will not idle. The rpms are all over the place. Won't stay running unless you give it gas, and then you have to play with the gas pedal to keep it running.

It gives no codes. When I unplug the MAF, it idles and runs fine. Great throttle response and idles fine. When I plug in the MAF, the condition returns. I replaced the MAF with the one out of my S80 (exact same part number on the MAF) and it does the same thing. I bought a new one, and plug it in, and it does the same thing. Unplug it, and it runs fine. I don't know what my next step would be. DO I check the temp sensor, TPS? Any help would be greatly appreciated. Thanks,

Bill

Could it be a short in the MAF sensor wiring?
