Chrysler Pacifica - 3.6 Pentastar Spark Plugs Replacement at 90K Miles

[Elroy the Brave]

Did the plugs fix this issue?

I once had this issue and fuel filter replacement fixed it.

Not really. The idle is still a bit "stumbly" at idle when the air conditioner is running. But, no check engine lights and everything is running fine. So basically the same as before I changed the spark plugs and coils at 90,000 miles.

It might be from a worn engine mount.

There is no serviceable fuel filter on this vehicle.

Did you move the 3 coils that were under the intake to the other bank and the ones that were out in the open now under the intake. I have read on jeep forums this will add significant life to them as the ones under the intake fail 40 to 50k earlier than the others (due to heat).

Interesting, is this the reason for the rodent snack tray under the intake?

I discard it regardless because IMO rodent damage weighed against any benefit ....the rodent damage is the greater risk -- at least around here.
