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...


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.

You should also swap the transmission if the motor is going to be more powerful. Also a new computer will be needed for the swap. If you are looking for an easy swap then just find the same motor.

How do u change the supercharger oil?


To change the oil on the supercharger that Buick Riviera is equipped with first remove the plastic cover directly over the supercharger. Next, stand on the passenger side of the vehicle and face the engine. You will be looking at the front of the supercharger. The oil fill port is located on the front portion of the supercharger along the right hand side as viewed from your position. It is a large hex plug. This is both the drain port and fill port. There are several ways to drain the oil. My personal favorite is a piece of rubber tubing and a large syringe. I have found this to be the quickest way. Once you have drained it use a funnel small enough to fit the fill port and take your time filling it. Fill it to just below the threads at the bottom of the oil port. Be careful not to overfill it. After you have replaced the oil plug I like to disconnect the coil wire. This allows the engine to turn over but not start up. It helps to circulate the new oil through out the supercharger that were drained dry. This is not required however. It is my own personal preference. From this point it's ready to go.

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
