Hi, I hope that you can help. My Caravan (3.3) shows a code that the 6th cyl. Is misfiring. It also pings and pops loudly when it is under load or when I am stepping on it to pass a vehical. I checked the compression on that cyl. It is fine, I replaced that plug and wire, nothing changed. My father thinks that it is backfiring. One more thing, when I go up hills it seems to miss, or chug a little while making this pinging and popping. The sound is getting more frequent. What can I do or check to stop this?
