Start in the center and work your way around in a circular pattern. Torque in 3 stages with the first stage just to feel them touch, then to about 20 ft./lbs, then to about 40 ft./lbs on the final step. Almost any repair manual would have the exact pattern recommended by the manufacturer.

How do you know if Intake manifold gasket is bad?

You will feel a miss at idle and the idle speed may be erratic. Try retorquing the intake manifold bolts, working from the center out in the recommended tightening sequence. If that fails, the intake manifold will have to be removed and the intake gaskets replaced.
