While you're in there, I'd go ahead and clean the MAFs (super-easy job; all you need is a big Phillips screwdriver and some MAF cleaner).

But that's just a shotgun "fix" - do some data monitoring/logging to help pinpoint the problem.

I'm going to be tearing into the car pretty soon. I'll hit the TB's and MAFs at the same time. I figured 55k on the ol' lady it's about time I clean them too but I wasn't sure if it was possible if the TB's (or MAF for that matter) could cause a dip in RPM.

I'll snag a video later so you guys can see what I'm talking about.
