Re: 3100 Upper plenum doent sit flat on lower
If the car was working before it must have been flat therefore something has changed during your R & R. Have you torque all the intake bolts down? Did you accidently leave a bolt on the intake? Did you properly route the MAP sensor in the back of the plenum? A gasket goes between the intake and the plenum therefore you must have zero gaps to seal. Look around the area that is high and you'll find your problem.
