I finally found a shop that uses the motor vac for cleaning the fuel injectors. They charge $109 and he said it'will take about an hour to do it. He also have an "OTC" which works like motor vac.
Steve (from Gainesville,FL) the shop's name is Conrad Auto repair and it's located in Beach Blvd, Jax. You can call him at (904) 641-0909. I'll be taking my rig there on friday.
