My 2008 lacrosse misfiring


Asked by Jan 16, 2013 at 07:59 PM about the 2008 Buick LaCrosse

Question type: Maintenance & Repair

I replaced plugs and wires to find the 4-1 coil had no spark so I replaced it. After 30 sec it started misfiring again tested it and their is no spark on that coil again. Before all of this the car would start at all but after siting in the garage for a day it started but was misfiring. Could the icm be the problem
