Default Information please

A week ago Saturday, the battery died in my 2005 Monte Carlo LS. Last Sunday, I put a new battery in. Started right up. I then drove the car to work the next morning with no problems. Monday afternoon, when I was leaving the car started acting up. I got about a mile up the road when I decided to pull into a parking lot. I had it towed to a garage. The garage only told me that the car is misfiring on all 6 cylinders. Today, they are going to pull the plugs and check compression. Is all this related to my changing the battery? Why would my car be misfiring on all 6 cylinders all of a sudden like that?

If it is true that it is misfiring on all cylinders, I would wonder if weird timing with the battery, but perhaps the ICM is failing.

That is strange they'd start with a compression test. The odds of finding the culprit there are virtually zero unless we're missing a piece of the background story. It's just not one of those things that's ok one day, and bad the next (unless the engine blew up lol, but you'd know if you blew the engine).

I'm with Maniac - the ICM is a good place to start, with a review of live pcm data being a good second step.
