    you know how you can test those. i have a 88 oldsmobile 3800 v6 and you can start your car, take the handle of a screwdriver and tap on the sensor. if it stumbles or dies then the sensor is bad. oldsmobile like mine will fit your car, pontiac around your year should fit also. i don,t know if chevy is the same or not.

    If that is a factory built supercharged Regal, there should be the correct MAF available. If that is an aftermarket supercharger, just slap the old one back on because your check engine light won't go out anyway,

    it will not idle or rev.

    to verify it, connect a scan tool.

    but the check engine should lit if any sensor fails.

    then by connecting a scan tool, you will know which sensor failed
