= How do you reset change oil soon light on 1993 buick park avenue? =
my 1993 buick park avenue wont start after i changed the front motor support you can jump it from the sodinoid and it will crank whats wrong could it be the security system
The Buick Park Avenue Started In 1991
The 1993 Buick Park Avenue Ultra produced 205 horsepower and 260 lb-feet of torque.
EGR Valve
The 1997-2005 Buick Park Avenue's and Park Avenue Ultra's all use the same bumper cover part number. So I think the bumpers themselves would be interchangeable.
Trouble code P1133 means:HO2S insufficient switching
how to reset the batterie light
overheated and/or no or low oil. oil pump went out
start by taking the door panel off ....
Mounted on top and inside the fuel tank.
Depends on the engine the Park Avenue had in it.
