2000 durango was driving fine then seemed to lose power and die and won't restart easily. It sputters and backfires, occasionally will rev up but won't idle on its own. What do I look 4?
What is the actual code number? If it is actually a cat code and you have had it for three years I would start there. Cat probably all stopped up now. And what you are discribing as symptoms sounds just like a stopped up cat. Use caution failure to replace or remove a stopped up cat can lead to your vehicle going up in a big ball of fire all of the sudden. Stopped up cats can get glowing red hot and set vehicle on fire.
