Two problems related to fuel injection have been reported for the 1999 Buick Park Avenue. The most recently reported issues are listed below.
Received recall notice for 99 Buick concerning injector regulator. Had to replace entire engine due to the problem. The rupture of the intake mainfold leak caused fuel and water mixture, the water on the top pistons caused the engine to lock, then the starter ceased and burned out.
The morning of December 13th, 2003, my father (james) started his 1999 Buick Park Avenue in the garage. Upon turning the key, he heard an explosion. He opened the hood to find the engine compartment engulfed in flames. He then pushed the car out of the garage and called 911. The police and fire department came and put out the fire. One of the firemen, who works on cars, told us that he had worked on 2 other cars that experienced the same thing. Colin hames.
