My car is still screwed up, so bad now that after about 45 minutes of driving it won't go over 2000 rpms. It's the weirdest thing I've ever seen. Dave, Tampa99GT, and I changed the fuel filter yesterday and checked the fuel pressure while it was idling and reving in the garage. Scott, you'll be proud to know I finally broke down and put a K&N in it and bagged the paper filter as well.

On my way home from Daves it started messing up about 45 minutes in. I'm thinking it's most likely the fuel pump. If it's not that a guy at a parts store suggested it could be the DPFE sensor. He said it's very common on 4.6's. The thing is I don't want to keep pissing money away chasing gremlins. If someone knows a shop that will diagnose it for me in this area I'd appreciate it.
