Check the emissions sticker under your hood to be sure, but timing should probably be 10* with spout removed.
This may sound off the wall, and I can't explain it. I replaced the RABS sensor on the rear diff today ($20 part and 2 minutes to change). It got rid of the initial hesitation in my truck.

No promises - just telling you what happened on mine (and I don't understand anything about it!) From what I can tell, it supplies rear wheel speed into to the ABS system, but it must give some info to the ECM as well.
It's the Rear Anti-Lock Brake Sensor. It's mounted on the top of the rear differential. One wiring connector, one screw, pull it out.
