Update: Thanks for all your suggestions. I Apologize for the delay, It's been hot here so I haven't been in the shop much and this is a spare car, but I rewired the throttle servo and that took care of the hesitation in the car. It passed emissions now too on first try. Here are the results: HC-0.38 out of 1.00,CO-2.29 out of 12.00,NOX-0.57 out of 2.50. The car runs pretty good now too, just one problem left..the idle speed sometimes drops low enough at a stop sign to kill the engine. I haven't had time to look into that.
