I have a Lumina 2004, in november 2006, it stalled while driving, took it to a workshop, they tested and changed egr sensor valve and ignition module. Then it run for few thousand kms, car stalled intermittently, then workshop checked and changed crack sensor. After a month, the car stopped again while i am driving. Now they said, Ignition module has to be changed.
Anybody can tell me, what could be the reason, i have faulty ignition module twice within 6 months? Do I need to change the coils? spark plug cables? please help
