You cant check the MAF without a special adapter harness from VW. You can use your Scan tool to check range..
Hope this helps..

it all checks out....
Well, I checked and everything is within spec. I watched the 02 sensor voltages when the problem happens, the voltage starts at 0.8, then drops to around 0.1, so it's going major lean. I checked the injector times, and they are at 16.x ms, and is the same when it is running right.
I don't understand it, if I let up just a little, it goes away. It's almost as if the fuel pressure drops, then kicks back in. Maybe the fuel pump gets shut off? Is there a way to tell?
