[V8] To rich and backfiring above 1700 rpm

Thanks Justin, it is definitely something I will keep in mind. It just doesn't make sense to me though, because if that is the case, why doesn't it run bad at idle, or 1000 rpm, 1100, 1200...ect..unless the missing teeth decide to go missing above 1700 rpm? For instance because it gets to chilly at higher rpm's? *G*

  It seems like this could be caused by a few missing flywheel teeth.  Another lister had similar symptoms with that problem.  It might even cause a reference sensor error code.  If you have a 27 mm socket this is easy to check.  To view the teeth jack the front of the car up a little and, with a flashlight, peek through the drain/inspection holes in the bottom of the bell housing.  Have someone else turn the engine clockwise using the 27 mm nut on the front pulley/dampener.  Other than that I don't know what it could be...maybe fuel pressure regulator?
