The Sensor pressure module on my 02 ZR2 is loose on the top of the plenum.
This goes directly into the intake, should it be able to have so much movement up and down and be able to wiggle slightly? I would think it should be a snug fit and not be able to move. can this cause a vacum leak and trigger a Multiple Misfire code?

 

New red gaskets can be had for ~ 5-6 bucks delivered. A cheap enough "fix" to try. If it is real loose, yes you might get a vac leak.

 

Yeah it seems to move around pretty good. Im replacing / upgrading to the MPI spider this week so when I have the upper plenum off I will give it a good look see. Thanks.
