My Ride: Too many to list
Chalk up another bad DISA valve, pulled it out last night and it nearly fell apart in my hand. Pulled the metal pin out with ease, glad it didn't fall out in the intake! The seal was definitely causing a vacuum leak as well, I'm thinking this was original, and at almost 120,000 miles, it sounds like it was due.
Put a new one in (as well as cleaned the MAF, that thing was nasty!) and it runs like a dream now.

Thanks again guys!
