So before I go buying 10 new coil packs I will test them first.....How many ohms should they read when tested with the meter. I am finding ranges 1.1-1.3. Old or new they are all reading the same. So look my plugs are AWFUL...changing this for sure.

 

I would only change a coil pack that has been proven to be bad by moving it to another cylinder to see if the miss follows it. There is no good reason to replace a COP that isn't dead, they tend to last for a long time.

 

Renew all the grounds to help prevent cop problems The ground strap to the battery corroded and no one noticed it. A scanner with a code
$6 misfire counter is the easiest way to diagnose a bad coil. I use Bluedriver.

I had no luck with preemptive replacement.
