'99 LeSabre - stalling problems
I have a 1999 Buick LaSabre that began stalling when it was hot and the outside temperature was hot. Now it stalls when cold also and the car seems to want to cut off sometimes when driving. Sometimes it will crank back up on the first cranking attempt and sometimes you must wait up to ten minutes. It will sometimes cut off when I take my foot off the accelerator and come to a stop. I have replaced the crank sensor, MAF sensor, EGR, and fuel filter. Replaced fuel pump about two years ago. I do lots of stop and go driving. What could be the problem? Thank you.
