PM sent, thanks. JayI changed mine; its takes about one hour for the entire process; there is a specific pattern for torque requirements on the air-intake manifold......I did a short write up on one of the posts about my experience. If you do not find the torque settings in the search PM me and I will look them up in the Service manual. By the way to save time, the fuel rails can be set aide with the injectors mounted. I also did not have to remove the quick connector at the fuel junction -just moved aside. The gaskets are re-usable.....
