The manual doesn't show a torque sequence, but it does list the torque at
11-14 ft.-lb. In general, you want to start in the center and work
outward when tightening the bolts/nuts.
Once you've entered the vehicle model and year in the service information
section, select the shop tab, Engine Mechanical, Intake and Exhaust
System, Intake Manifold, and the top INSTALLATION link. Although the
information is sparse, it does have some pictures and the torque
information at the top of the page.
