Hi new to the forums. i own a 87 deville handed down 3 generations. 45k miles however today replacing the airfilter and plugs noticed the gasket type thing under the tbi carb is destroyed and leaking air. i removed it not relizing it is a electronic piece type spacer. anybody know if the still make those or are they not needed? two holes mesh type scrrening and a connector. fits inbetween the intake manifold and the tbi carb deal. sorry not familair with this car or the workings of it so excuse my ignorance.

Mass Air Flow Sensor......not sure what the availability is for a new part. You could just replace the gasket and hope for the best if you have no codes coming up pertaining the this part. Pull the codes just to see if any problems areas exist.
