The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

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 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.

Stalls all the time and sometimes runs like it has bad gas it always starts right back up, but now 2-3 times a day when I get in and start it , it wont even turn over and dashlights all come on but just bought a new battery

When I open the door, a buzzing sound is heard, its over toward the glove box. When I turn the keys on to start, car goes completely dead. True jumping it, same results. I can remove keys, wait, try it again, same results.

I really don't care about any of the features. I was just in an accident today in my '94 lesabre and came away with barely a dent, the other car was totalled, and everyone came out just fine. I love my car, even though it may be dinosaur like at some points I really don't give a jizz because it saved mine and two other lives today. Dinosaur lover

As long as you take care of this vehicle it is a nice vehicle to own. The only down fall is the quick rust on the bottom of car and high cost of maintenance.

Very nice car but the bad mileage is TOURIBLE! I bought it from 5 days ago. very helpful and comfortable car like a boat! But I didn't know what the 10 mpg caused by? It chocked me!
