Well dude at this point only "The Man" knows whats up with your Rx. Theres not enough information in your post to make a diagnotstic guess but I think this is up:
1. How hard did you push her on the drag strip? These cars stock with low mileage can
take a lot but you may have "blew it" out there
2. I would not have replaced all of those parts without some diagnoses that they were
bad to start with.
3. Could be anything, but my best guess without further hard info is you must have
screwed up the engine somehow, perhaps blew an apex or something.
