My '98 Park Ave is equipped with factory installed air ride suspension, Buick calls it "Dynaride." There should be a badge located on the dask somewhere, or on the steering wheel saying either "Dynaride" or Dynaride equipped. There are other ways to tell, but that's the simplest.
The Buick Park Avenue line is known for its smooth ride. The suspension is an air ride, giving a soft floating feel.
Check in the air filter housing.
just in front of the air intake on the 92 park avenue supercharged model not sure on the standard 3.8 liter
On a 1997 Buick Park Avenue, the air conditioner drain hose is located under the hood and on the front of the firewall. It can be easily found by following the exhaust pipe from the catalytic converter on the passenger side up to the engine bay.
The 1991 Buick IAT sensor can be found in the air intake hose. The IAT sensor will be between the air box and the top of the engine.
Air shocks on a Buick Park Ave are adjustable to give a smoother ride. If a shock or compressor fails, the rear of the car will sag an possibly drag on low road bumps.
I have an 89 Buick electra park avenue, and I have averaged 23.3 over the last 2 weeks, using the air conditioning, and with a fair amount of in-town driving, but probably 80% highway driving.
Purchase a Purolator cabin filter. It comes with complete instructions.
The mass airflow sensor and intake air temp. sensors are between air filter and throttle body
On my 2000 Park Avenue, it's right in front of the radiator just below the hood latch mechanism. - GEO
