In your last thread you mentioned replacing the IAC, TPS and now coil packs?
What problem are you chasing ? Hard starting or bad idle etc ???
Did you replace the Spark Plugs & gap them yet..??

After 100k miles I would change coil packs out as a tune up item, just to be on the safe side.
I used the standards and are good alternative to the expensive Mopar's, but the Mopar coils will always be preferred.

Thanks again for the help and info. Very much appreciated. Chasing a hard start and rough idle.

I am starting with the plugs (NGK), cleaning the PCV, and replacing the IACV and TPS as needed, which got me to wondering about the useful life of the coil packs.

I was having a very rough idle after a 5500 mile road trip. New plugs and coil packs were the ticket to it being smooth again. It had also just passed 200k and I couldn't remember ever replacing them myself, and replacing the coils was exactly what it needed. I also cleaned the TPS, but it was pretty clean to begin with so I don't think my issue stemmed from that.
