2000 Buick LeSabre Custom 3.8L Misfire
Posted to GM Driveability on 12/30/2014 32 Replies

I have repeated ignition module failure on this Buick. All powers and grounds test good. I have replaced all coils, plugs, and wires. Car will run great for about a month and then will not fire on one or more coil pack. If i replace the icm it will run perfect...
