Depends what is wrong in the ICM. If the a trace to a coil internal on it has degraded, the car will run, but more then likely mis-fire from weak or no spark.

Best thing to do is have the ICM tested on a bench, it's a free test.

 

I'LL refer to something Jason "The_Maniac" said, and said to me when I had the same problem and the same readings from the auto shop. Coils don't. Normally go bad. If you do have a bad one then replace that one.
I do suggest removing the coils with the wires still attached. 5.5 mm socket. The plug order is 1 and 4, 2 and 5, and 3 and 6. Your original coils are marked. But the new ones may not be. The ICM is easy too.
Be sure to use the new rubber grommets the fit over the electrodes of the ICM. THE old ones may Also have degraded from heat.
My Monte had a bad 2 and 5 coil. I replace all mine cause the Electronic Technician in me would not let me replace only 1, But The _Maniac is right, it's not nessissary to replace them all if only one is bad.
As for the cost to have the shop do it, Pepboys was only going to charge me $429 if I let them do it. I thought that was expensive. It's a Really Really easy job. You can get to job sdone in a half hour under your favorite shade tree. So do it yourself. Good Luck and Safe driving!

 

When you have it tested have them repeat the test several times in a row so the ICM gets hot. Heat causes expansion and a lot of times an ICM will pass a bench test but fail once back on the car exposed to the under hood heat.

Good mention 03SSLE! I forgot about that, but very important (unless it fails on the first crack).

 

Thanks to everybody that helped I took my coils and module and got them checked and the module was bad all coils were good. Thanks again to everybody...

 

Glad it was something simple, and hopefully very cheap!

Never be afraid to ask how, and usually things can be done with very basic hand-tools.

 

The part was only 152.00 labor free done by me and that's better than 800.00 the shop wanted...

 

You have passed your Initiation into Monte Carlo Enthusiasm. You fixed your car. Now you are 1!

 

Awesome!!! Glad this one was solved easily

I find a DIY fix that goes easy just makes me feel good
