It says Buick Ultra... = Supercharged
Used Premium Gas
just in front of the air intake on the 92 park avenue supercharged model not sure on the standard 3.8 liter
No, it is an Ultra which means it is a supercharged 3.8L V6 and the 1995 Regal was a non-supercharged only so no. The supercharged models had an HD transmission and the Regal had the "regular verison". the transmission for the ultra was the 4t65e
If you put it on your self. The pump cost about $40.00
The super charger was only available in the Park Avenue.
This involves removing the gas tank from the car....not something you want to do in your driveway.
Bad plugs, bad wires, pluged fuel filter, dirty air filter...
how to reset the batterie light
Ultra is supercharged. the supercharged edition has more 'umph' when you punch it but it costs more and is is very expensive to service these units. Also, they should use premium fuel. My Mom has a n Ultra and I have a regular one. They feel the same to me when driving normally and I like the gas mileage mine gets (35 on the highway when driving less than 60 MPH).
For model year 1989 General Motors did not produce the Buick Park Avenue. The soonest production date to 1989 was the 1991 Park Avenue. The 1991 Park Avenue was offered in 3800 engine in supercharged or naturally aspirated. The part numbers for electronic control module (ECM) or "computer" will vary based on the exact engine for model year 1991s.
