Thanks.

I will check the Tank Vent Valve.....it's right in front and easy to check. I gather it should normally be closed ?

I have been clearing the codes and driving over the weeks.....they come back with high repeatability. The SEL take 20-40 miles though.

Last; when I pull the DISA valve, I'm a little surprised to find a bit of sand/grit in the oil film on the inside. That surprises me that grit would get through the air filter....but not impoisible.....it had been in Las Vegas and came with a lot of sand in the engine bay and in the bottom (dirty side) of the air filter box. I mention this because it would imply a source of vacuum leakage. But if there is a leak.....it must be small.

I'll drive for a while and then smoke it. If I can get my hands on another 2.5i, I'll try and swap the MAF.....but at over $300......it would seems like a bad bet/buy at this point.

Thanks,
Mike
