It is every other cylinder. ( #1, #4, #6, #7)
When I initially started this thread, I thought my mechanic said it was it was numbers 1,2,3,4. Sorry about that.
So, since it is every other cylinder, I can conclude that it is definitely the ignition module?
Thank you for your help
PS: I want to mention, that before this happened, the car was running great, with the only thing worth mentioning was a slight hesitation on occasion.
