I had the same problem with stalling & found the throttle sensor helped. It was only a $15 part @ an aftermarket parts supplier. You'll need small fingers to get to the few screws holding it in place. Also make sure it's positioned correctly before installing & tightening the screws.
Good Luck!

Fix is either throttle position sensor, mass air flow sensor, fuel pressure regulator , or fuel pump. Have fuel rail pressure tested.

Hello lysiphlebus2,

((My thoughts: cold START valve IAC at very bottom))

Plenty of places will do FREE diagnostic code reads.

I would rather suggest it be a muffler shop than
AUTOZONE... but either is better than guessing.

AUTOZONE will likely make you buy OXYGEN
sensors... (but that makes about as much sense as
buying a new THERMOMETER every-time you
have a FEVER.

What you are describing sounds (from an old
mechanic's perspective) like a collapsing
catalytic convertor or rotted muffler baffle
(a slightly better blockage will halt operation
completely)...

((again speculation... get your codes read))...

Do not buy OXYGEN SENSORS....

Know your prices before waltzing into any
exhaust shop.

Noise coming from turbocharger


1995 riviera is not turbocharged; it is supercharged--big diff; if the noise sounds like rocks tumbling, then you need to replace the plastic coupler in the supercharger; part is cheap -;labor is a lil high; it is a pain because you have to remove the alternator bracket on the buick version of the 3.8

Yea


IF YOU PURCHASE A CHEAP TESTER AT YOUR LOCAL AUTO PARTS STORE, YOU CAN ELIMINATE TWO OF THESE POSSIBILITIES. IF YOUR HEADLIGHTS WORK THEN CHANCES ARE THE BATTERY HAS ENOUGH JUICE TO CRANK THE ENGINE. IF ALL YOU HEAR WHEN YOU CRANK IS A CLICKING SOUND, THEN CHARGE THE BATTERY. IF YOU DON'T HEAR ANYTHING WHEN YOU TURN THE KEY, THEN CHECK THE FUSES. YOU MAY HAVE A BLOWN FUSE UNDER THE HOOD. IF THE CAR CRANKS AFTER JUMPING THE BATTERY, THEN LOOK TOWARDS AN ALTERNATOR. I HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR USING FIX-YA AND FOR AN HONEST RATING.

Wanna know if i can put a tranny for basic 1995 riviera in my Supercharger


you will most probably need a beefed up tranny to take the power of the engine, I have just installed a 350 supercharged chevy motor in my sons car with a Turbo 350 transmission and a shift kit which I have been told by an auto trans mechanic may not take the power of that engine.
It is costing him $1500 australian to have it reconditioned so I hope it will survive the rides
