I've been getting these errors, and did some logging and was wondering if anything stands out. My car is stock and I've just replaced Bank 2 EGT, Coolant Temp Sensor, BPV's TBB. Things that I've replaced that I don't think are relevant, valve cover gaskets, cam and crank seals, cam adjuster seals timing belt. BTW 17547 was happening before I did any work.

Here is a log of blocks 003, 031, 115. If I need to log something else let me know..

Did you check the hose running from under intake y pipe to fuel pressure regulator?

and forgot to list it.. If not no I didn't and will check it.

Only hitting 160-180 at 5200 or so? I think your MAF is crapping out, do you get any load table error codes? Try cleaning int with some carb cleaner, sometimes debris and oil build up on wire.
I have had 50% luck cleaning them.

logs I did in March/06 and MAF was running higher. Will try cleaning the MAF and see what happens. I have gotten intermittent misfires but since I did the engine work and reseated all the plugs the misfires have disappeared. Bank 1 precat throws a code once in a while. I don't think thats related.

skidmark

Yes, that's it.

Been long time since I've seen stock MAF readings,but since you said it I think I recall around 200+

....your pull was in but a 3rd gear pull should read at around 220g/s. 2nd gear will be a little lower.

As Ex said, it's an airflow problem. The 2.7T has a MAP back-up program in the ECU. There are two easy ways to check your MAF (neither are fool proof):
1) You can unplug your MAF and then take the car for a drive and see if there is a big performance difference. If there is your MAF is dead.
2) You can also log block 211 and compare the MAF to the MAP data in that block. If the flow numbers in 211 are significantly different...your MAF is dead.

If the MAF checks out okay above then look for an air leak post-turbo (IC hoses are a good start).

Good Luck!

Thanks.
