  1. Only 2003 models have cloth door panel inserts above the armrest and no black tint around the rear taillamps. Late 04 and 2005+ build dates have a extra scew at the rear section of the front door panels...early 04 build dates and all 03s do not. 2003 is the only year for a passenger door key hole.

  2. Run it with tha MAF disconnected. By doing so it should go to a speed density mode. If it runs better you most likely have a bad MAF or an air leak between the MAF and throttle body. The best way though would be to check the grams/sec pid on a scan tool or scope it with a dso.

     

    Since you dont have cats you can pretty much eliminate the possibilty of a restricted exhaust which would be my first guess with the video you presented.

     

    You said you replaced the fuel pump. I'd still like to see the actual pressure going to the rails. At mininmum 55 PSI.

     

    Of course it could just be a bad batch of gas.
