did you fit a new gasket, check for vacuum leaks, torquing the bolts in sequence is not super critical, just do then evenly.

You pulled the intake manifold just to change the spark plugs? Did you replace the gasket? 89 foot-pounds. Start on the inside and move to the outside.

There is a vacuum line that attaches right at the rear of the plenum that you may have missed.
