Hello, I have an 05 Century that has 167K on it and has run beautifully until, out of nowhere, it started having trouble starting, and was running rough. Then it stalled. So, I bulled a plug an it was shot, so new plugs and wires later, runs great :headbang:... for about an hour, then back to the same as before.:blink: Then it threw a code. I got it read and it was a random multiple cylinder misfire. I do not know where to go from here 😕, any suggestions? Any help would be greatly appreciated! 🙂
