Random miss fire code
Hey guys,
I have a 2000 DD with 120k on it, and it's served be well since I purchased it at 70k, no major issues besides normal maintenance, oil changed using fully synthetic every 3k. Just recently it started misfiring. I thought it was something connected to AC because it did it when I turned the air off, and usually kicked in when I was coming to a stop, then it would go away. (this just started a few days ago) Today was the first time it threw a code, and my engine light went flashing. it corrected itself again, and was fine the rest of the way to work this morning. I stopped briefly at the local auto parts and had them throw the code reader on it, it was a random misfire code, and there were 2 O2 sensor low voltage codes as well. Sorry if this has been addressed on here, time is of the essence, but I'm looking for suggestions on starting points. Also any other normal maintenance I should look into for a car with that many miles on it. Thanks!
