Symptoms of bad calpack?

When my coilpack went bad the car would pop and miss under heavy boost. Use an ohm meter and you should have between 11-13k ohms on each pack.

If you are referring to the calpack inside the ECM I had one that caused trouble. The symptoms were the car would start and then immediately shut off or idle quality would be very bad like someone pulled a spark plug. HTH
