1997 LeSabre is difficult to restart and idle when hot.

Asked by Jan 24, 2016 at 07:16 PM about the 1997 Buick LeSabre Limited Sedan FWD

Question type: Maintenance & Repair

This car has 190,000 on it but lately when it is up to temperature it does not
want to idle when started hot.  Starts and idles nicely when cold, but when hot
I need to keep it rev'd until it stabilizes in 10 to 20 seconds.  Frustrating
because it otherwise runs well.

It may be in the ignition control module, heat would affect it. The module can be tested at Auto Zone if you take it out, since it is a spendy part.
