I have a 1996 Lesabre. I had a similar problem that slowly got worse. I brought it to two different mechanics that did diagnostic checks and could only "suggest" what to replace to fix the problem. Their problem was that it wouldnt stall out while they had the mv. After replacing a bunch of sensors and the fuel pump/ filter, I solved the problem by replacing the Crank Sensor. Its located behind the lower crank pulley on the 3.8 lt motor. Hope this helps!

Take it to a real mechanic, not the phoney physics at the zone. The speed sensor will not respond if the car is not moving. May be an air flow sensor. They will go bad if it has ever been wet. They can be checked with a scan tool.

Sounds like you just need to replace the one or two 02 sensors on bank 1.If you have over 100,000 miles the 02 sensos are realy to be replaced just as spark plugs and air filteres. If you wait to long to replace them you take a chance of them not comming out and then when they do go bad you will need to replace the exhaust as well.Hope this helps and good luck.
