Any Ideas about COP problem
Ok so this last week I hooked up my new COP set up, there is only one problem, the car runs fine and when I accelerate it doesn't studder but when it is idling it will misfire randomly a little. like it will be purring and then go PLOP and keep going. Any ideas why this could be? I put in BPR7ES gaped @ .028 when I installed it too.

Those coils are used in 300m's so Idont know if there is a way chrysler tests them. I work at a ford dealer and we test our coils by using a scanner and adapters(vcm) to "stress" the coils which just puts a load on them and the tech inspects the graph.
You could just have a bad coil. Any cel?

I got random pops when i changed plugs to the ngk bpr7es also but after a month or so it didn't pop as much. Later i played around with the gap and it went away. Took out one plug at a time checked the gap played with it till i heard no more pop. Double check the gap mine was a little off like .3 on one of them and .27 on another.
