What did I do wrong with plugs?

Glad you got it figured out.

If you know anyone with a Mopar Superchips programmer, you can use the diagnostic function to read and reset codes (I use my Ram's for the Libby).

By the way, in case anyone searches for this later on, the check-engine light went off this morning. Evidently, the codes do go away eventually. Kept me from having to re-program the radio.

I believe the engine has to be started, warmed up, then shut down without fault about 5ish times before a code will magically disappear.

(OK somewhere between 3 and 10 times, the exact number escapes me)
