Question about Buick LeSabre
Your car is equipped with a computer
controlled engine management system. Scan your computer for fault or
error codes (most auto parts stores can do this for you, some will do it for
free or cheaper than others so call around before paying for it). The information
should pinpoint the malfunctioning components. Your idle speed control
motor is what I would look at first and think about replacing. The idle
air control valve may just need adjusting but with the car being this old, I
think it would need to be replaced, or idle air passage make have been blocked
off by excessive carbon build-up. If build-up is the problem, a good removal and
cleaning will do the trick or an off the shelf spray cleaner may get the job
done as well.
The EGR (exhaust gas recirculation) valve could also cause this concern. EGR is only commanded of idle and if this valve sticks open after driving it will cause an unstable idle or even a stalling. I would first check the idle air control valve though.
Let me know how this works out for you.
