1995 buick riviera 3.8 supercharged engine. Cold start issue. have to restart multiple times and it barely runs...spits back again and again until the engine warms up. once warm it runs correctly and starts easily. warm weather it has little problem starting. I am suspecting Mass air flow sensor or the temperature sensor...your thoughts???

you can not put a regular 3800 intake in place of the 3800 super charged engine,the compression ratio is lower than the regular 3800 engine.......!

if your supercharger sounds like tumbling rocks, it is the plastic coupler between the nose cone and the charger body; take off your serpentine belt; chances are the pulley has some play in it but it turns freely; the replacement coupler is a cheap fix; what gets a lil pricey is the labor to replace it... the buick has an alternator bracket that has to come off before you can take the nose off of the supercharger... dont forget to drain the oil from the nose cone with a spray bottle nozzle
