1998 Buick LeSabre Problems
The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
The water pump may develop a coolant leak resulting in an engine overheating condition.

1998 Buick Lesabre Custom - Piece of GARBAGE!!! Had to replace engine at 50,000 miles. Buick had to have their own Head Gasket!! Why? I have 1998 Chevy Lumina, 128,000 miles, starts right, up barely cranks over. The Buick, THEY HAD TO DESIGN THEIR OWN FUEL INJECTORS!! Couldn't use proven fuel injectors used in other 3.8L engines! Front sway bar snapped. Why? Both rocker panels are rusting out big time. Junk!!! Shocks failing miserably. Muffler too expensive to replace - welded system!! Not like muffler only!!
I bought a 1998 LeSabre 4 years ago with 60K miles on it. I now have 94K. The engine has been incredibly reliable. The only expense in 4 years was the serpentine belt at $125. However I have numerous problems. After running through a car wash I have a water leak but only on the driver side floor mat and only when it rains. Tried everything to locate problem to no avail. Horn relay stuck and now use a pushbutton wired to the horns. The AC/Heater control comes and goes. Never know when it will work. Seems to do better when car is parked in shade or when we have wet or damp weather conditions. Always starts with air blowing through instrument panel and then blows though windshield vents and stays there no matter what control I select. Thinking of replacing the control but will check with my mechanic first. The car drives great and have gotten 31MPG on the highway running 70s and with AC on. Can't afford another car and would like to get this one repaired.
Buick 1998 Lasabre 160k miles EMISSIONS AZ
Emissions +++ Emissions++++++++++
Arizona== Great used car but weird situation, it does not fail but it does not pass emissions. all lights on dash turn off after starting car so no problems according to car.
inspections says: catalyst, EGR and evap system NOT READY
and misfire, O2 sensor, ,heated O2, fuel system and component READY
dealer says Do a drive cycle which means drive it for 100 miles or more for computer to give new results but after 700 miles driven , still the same results.
if this happened to your car how did you fix the problem to make it pass emissions?
