1998 Buick LeSabre stalling.


Fuel trim will help,if the number are both positive at idle and go positive at a higher RPM you dealing with a fuel issue.There beem times the pressure regulator acts up,The EGR wont be the problem,you are stalling at idle,The famous crank,cam or ignition module,use a voltmeter or labscope measure the crank signal out put if its lower than 5 volts the ECM wont give a fuel signal.and the cam will not sychronize,I am going with the most popular failure a crank sensor as the solution,

1993 LeSabre- just started running rough mostly when put in reverse or drive. Not so much in park or neutral but a little, maybe cause of higher idle speed in park. Also runs a bit rough at slow speeds....


Sounds like the Torque Converter Lock-up Solenoid is failing. It will cause the car to run rough at slow speeds, and sometimes stall while idling in gear (at a stop sign for example)
To test this, locate the 2 or 3 wire connector on the left side of the transmission (looking at it from the left side of the car, it can be hard to find some times) Disconnect it. If the car runs and drives ok with it unplugged, the Lock Up Solenoid has gone bad. The solenoid itself is inside the valve body, inside the transmission (above the transmission pan)

97 buick lesabre 3.8 Idles rough and stalls out.


Fuel injectors go bad on these engines, you can find re manned ones for 30 bucks. If you have an engine light on get that read. Change your coil/wires/plugs also. Is the lower intake manifold gasket leaking coolant yet? You may want to get that replaced also. Check the TPS too (throttle positioning sensor) those will also cause your engine to act up

Car idles rough in park also runs rough in overdrive


Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

2000 LeSabre starts but runs very rough and stalls. After


Sounds like the plugs are not firing hot enough on initial start-up. Try a quick spark plug change, and clean throttle body. The gas being injected, isn't being burned fast enough by the plugs, which causes the car to have a hard start-up. You may try a higher octane gas or Lucas injector cleaner with your usual octane rating. Lucas comes in a very small bottle, and works very well in my opinion.

Its probably a vacuum line problem or EVAP or possibly the Mass Air Flow Sensor. Make sure that is hooked up as well. Examine all lines to see if there is a rip or tear or anything loose

1987 Buick Lesabre T stalling and running rough


I just had the same problem. Replaced the fuel filter,still crappy idle and no acceleration. I replaced the fump pump along with the wiring harness and the fuel pump screen and my cars purrs like a kitten,has back to normal acceleration and idles better than before. Hope this is some sort of help to you. I did it myself. Total cost, a little over $120. Good luck. By the way, your fuel pump should be pushing out about 65 lbs of pressure. is it ???
