1996 Buick Riviera Transmission proplems


The problem could be a minor miss-fire since the engine works harder between 40 and 50 mph when in overdrive than in other gears.
I would probably get a second opinion to eliminate the transmission.

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 need a tune up. Spark plugs; Spark plug wires; fuel filter (but you already replaced this) and air filter all need to be replaced. This should fix the problem.
